fixed canvas:clear() when multi-canvas rendering is active, changed some names and wording

Added MRT support to canvases via love.graphics.setCanvases(c1, c2, ...), and an 'effects' callback function in shaders.

Sun, 24 Mar 2013 02:20:15 -0300

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

The current transformation matrices will now be sent as uniforms to the active shader when rendering in ES2

A shader is now always active on systems which support shaders, no matter what; all systems with shader support now always use explicit generic vertex attributes (instead of glEnableClientState etc); GLEW now uses SDL's GetProcAddress function by default, instead of various per-OS functions.

Added love.graphics.get/setDefaultShader. The default shader is used when no shader is set, if shaders are supported. Any non-default shader will use the default shader's vertex or fragment source code, if it needs to. LÖVE will automatically set a 'pass-through' default shader when the window is first created.

Remove love_ScreenSize from shaders.

Mon, 01 Oct 2012 21:39:52 +0200

Remove love_ScreenSize from shaders.

PixelEffects would fail to load when screen_coords were unused.

Reopens issue #435: "PixelEffects have flipped screen_coords.y".

Fix #435 (for real this time). Unfixes #324.

Sun, 05 Aug 2012 16:08:22 +0200

Fix #435 (for real this time). Unfixes #324.

Add a extern vec2 love_ScreenSize to the pixel effects that will
be (re)set upon PixelEffect::loadVolatile() and is used to flip
the fragment coordinate.

Unfixes #324 because canvases can have different dimensions than
the screen.

Fix issue #435: PixelEffects have flipped screen_coords.y.

Fri, 03 Aug 2012 19:39:41 +0200

Fix issue #435: PixelEffects have flipped screen_coords.y.
