This will simplify the code and make it more maintainable when OpenGL ES 2+ support is added, compared to using the deprecated VA functions on desktop GL and the generic VA functions on GLES.

Returns the base type name ('float', 'image', etc.), the number of components (2 for a vec2), and number of array elements (1 for a non-array variable) for the extern variable with the specified name in the shader.
Returns nil if the variable either doesn't exist or was optimized out by the driver's shader compiler.
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.
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.
Each shader contains a map of uniform name -> bound retainable Object. After
setting the uniform, sendImage() and sendCanvas() release() the Object with
the requested name (if present) and record the new Image/Canvas.
Related bugfix: Shader::attach() calls retain()/release() on the shader.
