d2a1ff003b Fix text rendering issue. 
The local clip rect could be off by one pixel when a 3D transform
was applied to a text primitive. This would cause small rendering
glitches in Launcher in particular.

on its rendering.

eb07af6873 Optimize layer clears. 
Don't clear the entire texture when we use textures that are bigger
than the layer itself. This will save time during the glClear() calls.

This change detects empty quads in 9patches and removes them from
the mesh to avoid unnecessary blending.

0bb5667b4e Fix INVALID_OPERATION error with layers rendering. 
This change is a workaround for a driver bug that causes an INVALID_OPERATION
to be thrown on every glCopyTexSubImage() call. This change also adds a new
test for gradients local matrices.

1c740bce8a Document the implementation of saveLayer(). 
The implementation is simple but tricky. Leave explanations to my
future self so that I don't invent a time machine to come back to
now and slap my self.

This change also simplifies the way the GL blending function is
chosen when compositing a layer. It reuses existing OpenGLRenderer
APIs and is easier to understand.

Bug #2988077
This change keeps the 8888 format for new bitmaps and also keeps,
when possible, the opaque flag.
