Alex Szpakowski 88c8e0c071 Added an optional (true by default) boolean argument to love.graphics.setBlendMode to specify whether alpha should be multiplied with rgb when blending.
Removed the 'premultiplied' blend mode, since setBlendMode("alpha", false) accomplishes the same thing now.

The 'multiply' blend mode is unaffected by the new flag, since fixed-function hardware blending can't do the equivalent of setBlendMode("multiply", true).

Alex Szpakowski 275a9a300f Multi-canvas rendering (love.graphics.setCanvas with multiple canvases) now allows canvases with different formats, if the system supports it. Added 'multicanvasformats' to the table returned by love.graphics.getSupported.

Alex Szpakowski ac2b03e8a4 Added love.graphics.isActive. love.graphics function calls (and method calls on objects created via love.graphics) are only guaranteed to work when isActive is true, otherwise bad things might happen (the program crashing, for example.)
It's usually only false when the app is inactive on iOS, and when the window hasn't been created yet.

Alex Szpakowski b876255442 Cleaned up some graphics code. 2015-01-24 03:39:05 -04:00
Alex Szpakowski 970704c2b7 Added Text objects via love.graphics.newText(font [, textstring]). Reworked the internal code of Font objects to use fewer individual textures and less VRAM per object, and to be compatible with OpenGL ES. Slightly improved the performance of love.graphics.print and love.graphics.printf.
Text objects are Drawable objects that represent text on the screen. They decouple text drawing from text parsing and vertex uploading, in a similar manner to SpriteBatches. They also optionally allow efficient batching of text from the same Font in different relative coordinate transformations, without having many draw calls.

Text objects currently have the following methods:

Text:set(textstring) -- replaces any existing text in the object with the new string.
Text:setf(textstring, wraplimit, alignmode) -- replaces any existing text with formatted text using the new string.

Text:getFont() -- gets the Font object used for this Text object.
Text:getWidth() -- gets the width in pixels of the most recently added text in the Text object.
Text:getHeight() -- gets the height in pixels of the most recently added text in the Text object.

Text:add(textstring, x, y, angle, sx, sy, ox, oy, kx, ky) -- adds a new string to the text object using the specified relative coordinate transformation, without replacing existing text. This behaves much like SpriteBatch:add.
Text:addf(textstring, wraplimit, alignmode, x, y, angle, sx, sy, ox, oy, kx, ky) -- adds a new formatted string to the text object using the specified relative coordinate transformation.
Text:clear() -- clears all text from the object.

Alex Szpakowski 8ffe610659 Added love.graphics.getStats. It returns a table with performance-related graphics statistics. Currently it contains these fields:
drawcalls: The number of internal draw calls made so far in the current frame.

canvasswitches: The number of times the active Canvas has been changed so far in the current frame.

texturememory: The approximate amount of video memory (in bytes) used by OpenGL textures created by Images, Canvases, and Fonts.

images: The number of active Image objects.

canvases: The number of active Canvas objects.

fonts: The number of active Font objects.

Alex Szpakowski 2b70d84611 Replaced the old stencil API with love.graphics.drawStencil(stencilfunc), love.graphics.setStencilTest(enable, invert), and love.graphics.getStencilTest.
Draw to the stencil buffer (rather than the color buffer) using love.graphics.drawStencil with a function which draws geometry. Once the stencil buffer has been drawn to, use love.graphics.setStencilTest before drawing to let drawn geometry be affected by it.

love.graphics.clear (and Canvas:clear) will clear both the color and stencil buffers by default. love.graphics.clear("stencil") will clear only the stencil buffer.

Alex Szpakowski afc505e183 Added stack type enums to love.graphics.push (resolves issue #906.) Current enums are "transform" and "all". "transform" is the default (for compatibility.) When love.graphics.push("all") is used, love.graphics.pop() will restore all love.graphics module state to what it was when push was called.
Updated the graphics code to use a custom matrix stack rather than OpenGL1's APIs.

Removed the 'hdrcanvas', 'dxt', and 'bc5' graphics feature enums now that they're deprecated in 0.9.x in favour of getCanvasFormats and getCompressedImageFormats.

Alex Szpakowski ce4fdf4ac9 Added sRGB (gamma-correct) support for Images, Canvases, and the main screen.
love.graphics.newImage(path, “srgb”) creates a new Image whose texels are treated as being in the sRGB color space, so they are linearized when drawing/sampling from the image.

love.graphics.newCanvas(w, h, “srgb”) creates a new Canvas whose texels are treated as being in the sRGB color space, so drawing to the Canvas does a linear->sRGB conversion (but blends linearly), and sampling from it (drawing it or using it in a shader) converts from sRGB to linear space.

The "srgb" window flag does the same as Canvases for the main screen.

Alex Szpakowski 988404e4ca Added love.graphics.getSystemLimit (resolves issue #840). Deprecated love.graphics.getMaxPointSize.

Alex Szpakowski 73f1ce0d40 Added instancing support to Meshes via Mesh:setInstanceCount. Added a new built-in variable to vertex shaders: int love_InstanceID.
love.graphics.draw(mesh) will draw the mesh instancecount times, using hardware instancing when available. The only way to draw individual instances differently from each other is to use the love_InstanceID variable in a vertex shader.

Added love.graphics.isSupported(“instancing”). Hardware instancing is supported if true, otherwise a (slower) pseudo-instancing fallback is used internally when drawing instanced meshes.

Alex Szpakowski 113ed1cfe7 Merged SDL2 changes from bartbes/love-experiments/SDL2 into default.
- Added love.system module, including clipboard functions.

- Added custom hardware cursors (love.mouse.newCursor, love.mouse.setCursor.)

- Revamped love.joystick:
-- added Joystick objects and moved love.joystick functions which operated on individual joysticks to methods on the Joystick objects.
-- Added love.joystick.getJoystick and love.joystick.getJoystickCount.
-- Added events for when joysticks are connected and disconnected.
-- Added 'Gamepad' methods to Joystick objects: Joystick:isGamepad, Joystick:getGamepadAxis, and Joystick:isGamepadDown. They're a common abstraction for xbox controller-like joystick across operating systems.

- Added monitor choosing support and "fullscreen desktop" mode to love.window.

- Moved unicode text input events to their own callback function (love.textinput), removed the key repeat functions from love.keyboard and made the second argument of love.keypressed a boolean saying whether the keypress was a repeat.

- liblove now works with love.window and love.graphics in OS X

vrld be205544b3 Issue #659: Add line joins.
Added:

love.graphics.setLineJoin(linejoin)
linejoin = love.graphics.getLineJoin()

where linjoin is one of:

- none
- miter
- bevel

Bevel and miter drawing is slightly faster than the 0.8 default (miter), while
the `none` join mode will be slower when overdraw is enabled.

Alex Szpakowski 63404f7097 Added love.graphics.getRendererInfo(infotype). Useful for creating more informative error reports and advanced debugging.
Returned string can be highly system-dependent, so don't rely on its output!

infotype can be "name", "version", "vendor", or "device"

Alex Szpakowski 5301026f3c Added support for DXT1/3/5 and BC5/7 compressed textures via love.image.CompressedData. Some internals are still iffy.
- added a new CompressedData type to love.image
- added love.image.isCompressed(file or data)
- love.graphics.newImage automatically tests for compression when loading a file
- added love.graphics.isSupported strings for DXT, BC5, and BC7

Compressed textures meant to be used on the GPU offer huge performance gains when
- loading the texture from a file
- loading the texture from RAM to VRAM
- loading mipmaps
- rendering

Alex Szpakowski 2ea065c68b Added MRT support to canvases via love.graphics.setCanvases(c1, c2, ...), and an 'effects' callback function in shaders.
- Simultanious rendering to multiple canvases requires all canvases to be the same size (limitation of pre-GL3.0 framebuffers)
- love.graphics.isSupported("mrtcanvas") was added
- love_Canvases[n] (0-based array of active canvases) can be written to in pixel shaders in the 'effects' callback function
- everything drawn to multiple canvases at once will be duplicated to all canvases if no shader is active or the standard 'effect' shader function is used
