4bb942083a Optimize 9patch rendering. 
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.

9cccc2b9bd Enforce maximum texture size. 
When an app tries to render a bitmap or path larger than the GPU's maximum
texture size, the drawing command is ignored and a warning is logged. This
change also makes texture drawing more robust by catching potential errors
during texture creation.

This change also fixes a crash in the FontRenderer. The destructor would
sometimes try to free an uninitialized array.
