This feature needs support for renderable float textures, but the checks
were only guaranteeing support for float texture reads.

In some applications, the first draw is not opaque - either because the
application is misbehaved, or because hwui is not able to reliably tell
whether the layer is opaque or translucent. This is undefined behaviour
in OpenGL ES and has a significant performance and bandwidth impact on
some tiler GPUs as it requires loading the previous frame's color data.
This change disables blending in that case and also for effectively
opaque blend modes (SRC=GL_ONE, DST=GL_ZERO). It increases performance
by ~10% for Leanback CTS on some low-end GPUs (gradient layer that hwui
incorrectly believes to be translucent).

Apply correctly the image transform matrix passed to
SkiaOpenGLReadback::copyImageInto.
This is fixing 13 of 14 failing android.view.cts.PixelCopyTest
tests (the last failing test is caused by missing wide gamut
support).
Test: Ran CtsViewTestCases CTS tests for Skia and HWUI pipelines.

If the output matches the source rect then use
GL_NEAREST instead of GL_FILTER. This is a more
pixel-exact capture.

WCG windows render into RGBA16F surfaces, we need to give the readback
API the ability to read the raw source data for testing.

This configuration uses 64 bits per pixel. Heach component is stored as a
half precision float value (16 bits). Half floats can be decoded/encoded
using android.util.Half.
RGBA_F16 bitmaps are used to decode wide-gamut images stored in 16 bit
formats (PNG 16 bit for instance). aapt is currently not aware of PNG
16 bits so such files must be placed in raw/ resource directories.
This first pass provides only partial drawing support with hardware
acceleration. RGBA_F16 bitmaps are stored in linear space and need
to be encoded to gamma space with the appropriate OETF to be rendered
properly on Android's current surfaces. They are however suitable for
linear blending. Full rendering support will be provided in a future
CL (BitmapShaders might be a bit tricky to handle properly during
shader generation).
