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 15538426d7 Added support for creating OpenGL ES 2 and 3 contexts, and updated the OpenGL context creation code to be more robust in general.
If the LOVE_GRAPHICS_USE_OPENGLES environment variable is set, then love will try to create an OpenGL ES context before falling back to regular OpenGL. If it's not set (or set to 0), then the opposite happens except when love is run on backends that should always use OpenGL ES.

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 d59c76a55f Reduced the number of explicit retain/release method calls on love objects. Less chance of bugs! 2014-08-07 14:53:17 -03:00
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.

Alex Szpakowski 8483ea31a1 Changed love.graphics.newImage's optional second argument to be a table of flags. Current flags are 'mipmaps' and 'srgb'.
If mipmaps are enabled on image creation, the image will use the default mipmap filter (now 'nearest' by default.) Image:setMipmapFilter will error if the image was not created with mipmaps enabled.

The list includes RGBA with 4-bit components, RGBA with 10-bit R, G, and B components and a 2-bit alpha component, RGB with 9-bit RGB components and a 5-bit exponent component (for HDR rendering), and several more.

Alex Szpakowski caa61563cc OpenGL 2.1 is now required to use love.graphics (resolves issue #779.)

Alex Szpakowski 6259e38d84 Meshes will now use the smallest integer data type possible for index buffer (vertex map) values, instead of always using 32-bit integer numbers. 2014-02-12 02:22:57 -04:00
Alex Szpakowski b625bb6624 moved Mesh:setWireframe to love.graphics.setWireframe (affects all draws until it's disabled.)
Wireframe mode should only be used for debugging: the wireframe lines behave differently than regular lines, their widths aren't affected by the graphics scale, and the mode isn't available on OpenGL ES.

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 ba7e69d776 Added Mesh:setDrawRange(min, max) and Mesh:getDrawRange().
If no vertex map is set, this restricts the drawn vertices to those whose indices in the vertex array are between [min, max] inclusive.
If a vertex map is set, this restricts the values used in the vertex map to those whose indices in the vertex map array are between [min, max] inclusive.

Added Mesh constructor variant: love.graphics.newMesh(vertexcount, texture, drawmode). Creates a Mesh with a certain number of vertices with x,y,u,v,r,g,b,a values of (0,0,0,0,255,255,255,255).

Canvases and Images are now subclasses of the new Texture class.
Added setTexture and getTexture methods for Meshes, ParticleSystems, and SpriteBatches (the old set/getImage methods are deprecated but not removed.)
Canvas texture coordinates are no longer flipped.

Alex Szpakowski 1e696c4505 Added Mesh objects and love.graphics.newMesh. Mesh objects are similar to Geometry but they're drawables (the relationship between meshes and images is the opposite of geometry and images.)
Removed Geometry objects and re-added Quads.

example:
local vertices = {{0, 0, 0, 0}, {100, 0, 1, 0}, {100, 100, 1, 1}, {0, 100, 0, 1}}
mesh = love.graphics.newMesh(vertices, image, "fan")

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.
