drawColor() was not calling quickReject because it fills the clip region
and thus always passes the test. However, quickReject also checks whether
the current layer is invisible. drawColor() now performs the same check
and avoid drawing inside an invisible layer.

This optimization is currently disabled until Launcher is
modified to take advantage of it. The optimization can be
enabled by turning on RENDER_LAYERS_AS_REGIONS in the
OpenGLRenderer.h file.

This change batches calls to glScissor() and removes extra GL
queries and glActiveTexture() calls.

A change was made earlier in the renderer to not snap the current clip rect
on every clip operation. The clip rect must not be snapped to pixel boundaries
before being used for pixel precision operations. Some operations were doing
this correctly, others were not. For instance, a layer was always created by
rounding to the correct pixels, but composing a layer was done with a non
rounded clip, thus resulting in slightly odd behaviors.

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.

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.

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.

Add a glGetError() check on every frame
Don't attempt to create textures larger than the maximum size allowed

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.
