The comparisons used in the various properties setters could fail badly
in some specific conditions. The scale properties in particular did not
use the same comparisons.
This change also clamps alpha to the 0..1 range which avoids overflow
issues with lowp registers in GLSL computations.

Bug: 5327776
Currently LTE_FLOAT isn't even a valid partial order, let alone
a strict weak order as needed by binary search. Consequently,
KeyedVectors with keys whose types have operator< using LTE_FLOAT
sometimes find the wrong values!
This problem affects several graphics caches including the
TextLayoutCache.
(This is still not a total order because NaNs are not comparable
but hopefully we don't ever search for NaNs this way!)

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