A Geometry is a collection of vertices describing a non self-intersecting
(simple) polygon. In addition to screen coordinates, the vertices have
attributes for texture coordinates (s,t) and color (r,g,b,a).
It can be used as a quad, to display distorted images, or anything in between.
Added:
^^^^^^
-- geometry from table, where table has the format:
-- info = {
-- {x,y, s,t, [r = 255, g = 255, b = 255, a = 255]}
-- {x,y, s,t, [r = 255, g = 255, b = 255, a = 255]}
-- ...
-- }
geom = love.graphics.newGeometry(info)
-- convenience wrapper for quads (same as before)
geom = love.graphics.newQuad(x,y, w,h, sw,sh)
-- retrieve vertex i (1-indexed)
x,y,s,t,r,g,b,a = geom:getVertex(i)
-- set vertex i (1-indexed)
geom:setVertex(i, x,y, s,t, [r,g,b,a])
-- flip geometry
geom:flip(x, y)
Renamed:
^^^^^^^^
love.graphics.drawq() -> love.graphics.drawg()
Removed:
^^^^^^^^
quad:setViewport()
quad:getViewport()
- 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

- 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

Some additional overhead was added to newScreenshot because it doesn't use glPixelTransfer (not supported in ES2 / core GL3+, and like all GL functions has the slight potential to be buggy on some drivers). This choice might be revisited in the future.
- The "replace" color mode can easily be duplicated with love.graphics.setColor(255, 255, 255)
- The current color mode has no effect when a shader is active
- Color mode functionality can easily be replicated with shaders
- OpenGL ES 2 (iOS, Android, etc) does not have the functions used by love.graphics.setColorMode
setColorMask enables or disables specific color components when rendering and clearing the screen.
For example, setColorMask(true, false, true, true) will prevent the green component of the color of all rendered objects from being written to the current frame buffer.
setColorMask is a wrapper for http://www.opengl.org/sdk/docs/man2/xhtml/glColorMask.xml
