* There's also lots of good information here:

* \brief Load the audio data of a WAVE file into memory
*
* Loading a WAVE file requires \c src, \c spec, \c audio_buf and \c audio_len
* to be valid pointers. The entire data portion of the file is then loaded
* into memory and decoded if necessary.
*
* If \c freesrc is non-zero, the data source gets automatically closed and
* freed before the function returns.
*
* Supported are RIFF WAVE files with the formats PCM (8, 16, 24, and 32 bits),
* IEEE Float (32 bits), Microsoft ADPCM and IMA ADPCM (4 bits), and A-law and
* µ-law (8 bits). Other formats are currently unsupported and cause an error.
*
* If this function succeeds, the pointer returned by it is equal to \c spec
* and the pointer to the audio data allocated by the function is written to
* \c audio_buf and its length in bytes to \c audio_len. The \ref SDL_AudioSpec
* members \c freq, \c channels, and \c format are set to the values of the
* audio data in the buffer. The \c samples member is set to a sane default and
* all others are set to zero.
*
* It's necessary to use SDL_FreeWAV() to free the audio data returned in
* \c audio_buf when it is no longer used.
*
* Because of the underspecification of the Waveform format, there are many
* problematic files in the wild that cause issues with strict decoders. To
* provide compatibility with these files, this decoder is lenient in regards
* to the truncation of the file, the fact chunk, and the size of the RIFF
* chunk. The hints SDL_HINT_WAVE_RIFF_CHUNK_SIZE, SDL_HINT_WAVE_TRUNCATION,
* and SDL_HINT_WAVE_FACT_CHUNK can be used to tune the behavior of the
* loading process.
*
* Any file that is invalid (due to truncation, corruption, or wrong values in
* the headers), too big, or unsupported causes an error. Additionally, any
* critical I/O error from the data source will terminate the loading process
* with an error. The function returns NULL on error and in all cases (with the
* exception of \c src being NULL), an appropriate error message will be set.
*
* It is required that the data source supports seeking.
*
* Example:
* \code
* SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...);
* \endcode
*
* \param src The data source with the WAVE data
* \param freesrc A integer value that makes the function close the data source if non-zero
* \param spec A pointer filled with the audio format of the audio data

* device, you want SDL_QueueAudio() instead. This will always return 0
* if you use it with playback devices.)
*
* SDL offers two ways to retrieve audio from a capture device: you can
* either supply a callback that SDL triggers with some frequency as the
* device records more audio data, (push method), or you can supply no
* callback, and then SDL will expect you to retrieve data at regular
* intervals (pull method) with this function.
*
* There are no limits on the amount of data you can queue, short of
* exhaustion of address space. Data from the device will keep queuing as
* necessary without further intervention from you. This means you will
* eventually run out of memory if you aren't routinely dequeueing data.
*
* Capture devices will not queue data when paused; if you are expecting
* to not need captured audio for some length of time, use
* SDL_PauseAudioDevice() to stop the capture device from queueing more
* data. This can be useful during, say, level loading times. When
* unpaused, capture devices will start queueing data from that point,
* having flushed any capturable data available while paused.
*
* This function is thread-safe, but dequeueing from the same device from
* two threads at once does not promise which thread will dequeued data
* first.
*
* You may not dequeue audio from a device that is using an
* application-supplied callback; doing so returns an error. You have to use
* the audio callback, or dequeue audio with this function, but not both.
*
* You should not call SDL_LockAudio() on the device before queueing; SDL
* handles locking internally for this function.
*
* \param dev The device ID from which we will dequeue audio.
* \param data A pointer into where audio data should be copied.
* \param len The number of bytes (not samples!) to which (data) points.
* \return number of bytes dequeued, which could be less than requested.

* number may shrink at any time, so this only informs of pending data.
*
* Once we've sent it to the hardware, this function can not decide the

* Immediately after this call, SDL_GetQueuedAudioSize() will return 0. For

* isn't queued. Unpaused capture devices will start filling the queue again

* please follow these rules:
*
* - Try to use the same org string (including case-sensitivity) for
* all your applications that use this function.
* - Always use a unique app string for each one, and make sure it never
* changes for an app once you've decided on it.
* - Unicode characters are legal, as long as it's UTF-8 encoded, but...
* - ...only use letters, numbers, and spaces. Avoid punctuation like
* "Game Name 2: Bad Guy's Revenge!" ... "Game Name 2" is sufficient.
*
* This returns an absolute path in UTF-8 encoding, and is guaranteed to
* end with a path separator ('\\' on Windows, '/' most other places).
*
* The pointer returned by this function is owned by you. Please call
* SDL_free() on the pointer when you are done with it, or it will be a
* memory leak. This is not necessarily a fast call, though, so you should
* call this once near startup and save the string if you need it.
*
* You should assume the path returned by this function is the only safe
* place to write files (and that SDL_GetBasePath(), while it might be
* writable, or even the parent of the returned path, aren't where you
* should be writing things).
*
* Some platforms can't determine the pref path, and on other
* platforms, this might be meaningless. In such cases, this function will
* return NULL.
*
* \param org The name of your organization.
* \param app The name of your application.
* \return UTF-8 string of user dir in platform-dependent notation. NULL
* if there's a problem (creating directory failed, etc).

* \sa SDL_GetBasePath

*
* This file should be included as
* #include <KHR/khrplatform.h>
* by Khronos client API header files that use its types and defines.
*
* The types in khrplatform.h should only be used to define API-specific types.
*
* Types defined in khrplatform.h:
* khronos_int8_t signed 8 bit
* khronos_uint8_t unsigned 8 bit
* khronos_int16_t signed 16 bit
* khronos_uint16_t unsigned 16 bit
* khronos_int32_t signed 32 bit
* khronos_uint32_t unsigned 32 bit
* khronos_int64_t signed 64 bit
* khronos_uint64_t unsigned 64 bit
* khronos_intptr_t signed same number of bits as a pointer
* khronos_uintptr_t unsigned same number of bits as a pointer
* khronos_ssize_t signed size
* khronos_usize_t unsigned size
* khronos_float_t signed 32 bit floating point
* khronos_time_ns_t unsigned 64 bit time in nanoseconds
* khronos_utime_nanoseconds_t unsigned time interval or absolute time in
* nanoseconds
* khronos_stime_nanoseconds_t signed time interval in nanoseconds
* khronos_boolean_enum_t enumerated boolean type. This should
* only be used as a base type when a client API's boolean type is
* an enum. Client APIs which use an integer or other type for
* booleans cannot use this as the base type for their boolean.
*
* Tokens defined in khrplatform.h:
*
* KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
*
* KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
* KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
*
* Calling convention macros defined in this file:
* KHRONOS_APICALL
* KHRONOS_APIENTRY
* KHRONOS_APIATTRIBUTES
*
* These may be used in function prototypes as:
*
* KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
* int arg1,
* int arg2) KHRONOS_APIATTRIBUTES;

* USER-SELECTABLE CONFIGURATION MACROS
*
* This file contains the default configuration macro definitions for a
* standard build of the FreeType library. There are three ways to use
* this file to build project-specific versions of the library:
*
* - You can modify this file by hand, but this is not recommended in
* cases where you would like to build several versions of the library
* from a single source directory.
*
* - You can put a copy of this file in your build directory, more
* precisely in `$BUILD/freetype/config/ftoption.h`, where `$BUILD` is
* the name of a directory that is included _before_ the FreeType include
* path during compilation.
*
* The default FreeType Makefiles and Jamfiles use the build directory
* `builds/<system>` by default, but you can easily change that for your
* own projects.
*
* - Copy the file <ft2build.h> to `$BUILD/ft2build.h` and modify it
* slightly to pre-define the macro `FT_CONFIG_OPTIONS_H` used to locate
* this file during the build. For example,
*
* ```
* #define FT_CONFIG_OPTIONS_H <myftoptions.h>
* #include <freetype/config/ftheader.h>
* ```
*
* will use `$BUILD/myftoptions.h` instead of this file for macro
* definitions.
*
* Note also that you can similarly pre-define the macro
* `FT_CONFIG_MODULES_H` used to locate the file listing of the modules
* that are statically linked to the library at compile time. By
* default, this file is `<freetype/config/ftmodule.h>`.
*
* We highly recommend using the third method whenever possible.

* they do in a Windows ClearType (DirectWrite) environment. See [1] for a
* technical overview on what this means. See `ttinterp.h` for more
* details on the LEAN option.
*
* There are three possible values.
*
* Value 1:
* This value is associated with the 'Infinality' moniker, contributed by
* an individual nicknamed Infinality with the goal of making TrueType
* fonts render better than on Windows. A high amount of configurability
* and flexibility, down to rules for single glyphs in fonts, but also
* very slow. Its experimental and slow nature and the original
* developer losing interest meant that this option was never enabled in
* default builds.
*
* The corresponding interpreter version is v38.
*
* Value 2:
* The new default mode for the TrueType driver. The Infinality code
* base was stripped to the bare minimum and all configurability removed
* in the name of speed and simplicity. The configurability was mainly
* aimed at legacy fonts like 'Arial', 'Times New Roman', or 'Courier'.
* Legacy fonts are fonts that modify vertical stems to achieve clean
* black-and-white bitmaps. The new mode focuses on applying a minimal
* set of rules to all fonts indiscriminately so that modern and web
* fonts render well while legacy fonts render okay.
*
* The corresponding interpreter version is v40.
*
* Value 3:
* Compile both, making both v38 and v40 available (the latter is the
* default).
*
* By undefining these, you get rendering behavior like on Windows without
* ClearType, i.e., Windows XP without ClearType enabled and Win9x
* (interpreter version v35). Or not, depending on how much hinting blood
* and testing tears the font designer put into a given font. If you
* define one or both subpixel hinting options, you can switch between
* between v35 and the ones you define (using `FT_Property_Set`).

*
* @section:
* error_enumerations
*
* @title:
* Error Enumerations
*
* @abstract:
* How to handle errors and error strings.
*
* @description:
* The header file `fterrors.h` (which is automatically included by
* `freetype.h` defines the handling of FreeType's enumeration
* constants. It can also be used to generate error message strings
* with a small macro trick explained below.
*
* **Error Formats**
*
* The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be
* defined in `ftoption.h` in order to make the higher byte indicate the
* module where the error has happened (this is not compatible with
* standard builds of FreeType~2, however). See the file `ftmoderr.h`
* for more details.
*
* **Error Message Strings**
*
* Error definitions are set up with special macros that allow client
* applications to build a table of error message strings. The strings
* are not included in a normal build of FreeType~2 to save space (most
* client applications do not use them).
*
* To do so, you have to define the following macros before including
* this file.
*
* ```
* FT_ERROR_START_LIST
* ```
*
* This macro is called before anything else to define the start of the
* error list. It is followed by several `FT_ERROR_DEF` calls.
*
* ```
* FT_ERROR_DEF( e, v, s )
* ```
*
* This macro is called to define one single error. 'e' is the error
* code identifier (e.g., `Invalid_Argument`), 'v' is the error's
* numerical value, and 's' is the corresponding error string.
*
* ```
* FT_ERROR_END_LIST
* ```
*
* This macro ends the list.
*
* Additionally, you have to undefine `FTERRORS_H_` before #including
* this file.
*
* Here is a simple example.
*

* this constant.
*
* If the font is tricky and the glyph has been loaded with
* @FT_LOAD_NO_SCALE, the resulting CBox is meaningless. To get
* reasonable values for the CBox it is necessary to load the glyph at a
* large ppem value (so that the hinting instructions can properly shift
* and scale the subglyphs), then extracting the CBox, which can be
* eventually converted back to font units.
*
* Note that the maximum coordinates are exclusive, which means that one
* can compute the width and height of the glyph image (be it in integer
* or 26.6 pixels) as:
*
* ```
* width = bbox.xMax - bbox.xMin;
* height = bbox.yMax - bbox.yMin;
* ```

* bbox.yMin = FLOOR(bbox.yMin);
* bbox.xMax = CEILING(bbox.xMax);
* bbox.yMax = CEILING(bbox.yMax);

* @section:

*
* @title:
* Subpixel Rendering
*
* @abstract:
* API to control subpixel rendering.
*
* @description:
* FreeType provides two alternative subpixel rendering technologies.
* Should you define `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` in your
* `ftoption.h` file, this enables patented ClearType-style rendering.
* Otherwise, Harmony LCD rendering is enabled. These technologies are
* controlled differently and API described below, although always
* available, performs its function when appropriate method is enabled
* and does nothing otherwise.
*
* ClearType-style LCD rendering exploits the color-striped structure of
* LCD pixels, increasing the available resolution in the direction of
* the stripe (usually horizontal RGB) by a factor of~3. Using the
* subpixels coverages unfiltered can create severe color fringes
* especially when rendering thin features. Indeed, to produce
* black-on-white text, the nearby color subpixels must be dimmed
* equally.
*
* A good 5-tap FIR filter should be applied to subpixel coverages
* regardless of pixel boundaries and should have these properties:
*
* 1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid
* any shifts in appearance.
*
* 2. It should be color-balanced, meaning a~+ b~=~c, to reduce color
* fringes by distributing the computed coverage for one subpixel to
* all subpixels equally.
*
* 3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain
* overall brightness.
*
* Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less
* forgiving of non-ideal gamma curves of a screen (and viewing angles),
* beveled filters are fuzzier but more tolerant.
*
* Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights
* API to specify a low-pass filter, which is then applied to
* subpixel-rendered bitmaps generated through @FT_Render_Glyph.
*
* Harmony LCD rendering is suitable to panels with any regular subpixel
* structure, not just monitors with 3 color striped subpixels, as long
* as the color subpixels have fixed positions relative to the pixel
* center. In this case, each color channel is then rendered separately
* after shifting the outline opposite to the subpixel shift so that the
* coverage maps are aligned. This method is immune to color fringes
* because the shifts do not change integral coverage.
*
* The subpixel geometry must be specified by xy-coordinates for each
* subpixel. By convention they may come in the RGB order: {{-1/3, 0},
* {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},
* {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.
*
* Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.
* If one follows the RGB order convention, the same order applies to the
* resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps. Note,
* however, that the coordinate frame for the latter must be rotated
* clockwise. Harmony with default LCD geometry is equivalent to
* ClearType with light filter.
*
* As a result of ClearType filtering or Harmony rendering, the
* dimensions of LCD bitmaps can be either wider or taller than the
* dimensions of the corresponding outline with regard to the pixel grid.
* For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to
* the left, and 2~subpixels to the right. The bitmap offset values are
* adjusted accordingly, so clients shouldn't need to modify their layout
* and glyph positioning code when enabling the filter.
*
* The ClearType and Harmony rendering is applicable to glyph bitmaps
* rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and
* @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V
* is specified. This API does not control @FT_Outline_Render and
* @FT_Outline_Get_Bitmap.
*
* The described algorithms can completely remove color artefacts when
* combined with gamma-corrected alpha blending in linear space. Each of
* the 3~alpha values (subpixels) must by independently used to blend one
* color channel. That is, red alpha blends the red channel of the text
* color with the red channel of the background pixel.

/**************************************************************************
*
* This file is used to define the FreeType module error codes.
*
* If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
* set, the lower byte of an error value identifies the error code as
* usual. In addition, the higher byte identifies the module. For
* example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
* error `TT_Err_Invalid_File_Format` has value 0x1303, the error
* `T1_Err_Invalid_File_Format` has value 0x1403, etc.
*
* Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
* including the high byte.
*
* If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
* error value is set to zero.
*
* To hide the various `XXX_Err_` prefixes in the source code, FreeType
* provides some macros in `fttypes.h`.
*
* FT_ERR( err )
*
* Add current error module prefix (as defined with the `FT_ERR_PREFIX`
* macro) to `err`. For example, in the BDF module the line
*
* ```
* error = FT_ERR( Invalid_Outline );
* ```
*
* expands to
*
* ```
* error = BDF_Err_Invalid_Outline;
* ```
*
* For simplicity, you can always use `FT_Err_Ok` directly instead of
* `FT_ERR( Ok )`.
*
* FT_ERR_EQ( errcode, err )
* FT_ERR_NEQ( errcode, err )
*
* Compare error code `errcode` with the error `err` for equality and
* inequality, respectively. Example:
*
* ```
* if ( FT_ERR_EQ( error, Invalid_Outline ) )
* ...
* ```
*
* Using this macro you don't have to think about error prefixes. Of
* course, if module errors are not active, the above example is the
* same as
*
* ```
* if ( error == FT_Err_Invalid_Outline )
* ...
* ```
*
* FT_ERROR_BASE( errcode )
* FT_ERROR_MODULE( errcode )
*
* Get base error and module error code, respectively.
*
* It can also be used to create a module error message table easily with
* something like
*
* ```
* #undef FTMODERR_H_
* #define FT_MODERRDEF( e, v, s ) { FT_Mod_Err_ ## e, s },
* #define FT_MODERR_START_LIST {
* #define FT_MODERR_END_LIST { 0, 0 } };
*

* purposes (otherwise it would result in a visible dot when round caps
