Canvases can now be used in SpriteBatches, ParticleSystems, and Meshes (resolves issue #782).

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.
