Support RGBA fonts and bitmap fonts (and RGBA bitmap fonts)
Quite a few things going on in this commit:
- Enable bitmap strikes by default in Paint objects.
The SkPaint parameter that enables bitmap strikes was not previously
included in DEFAULT_PAINT_FLAGS. This effectively disabled bitmap
fonts. Oops! It's for the best, though, as additional work was needed
in Skia to make bitmap fonts work anyway.
- Complain if TEXTURE_BORDER_SIZE is not 1.
Our glyph cache code does not currently handle any value other than 1
here, including zero. I've added a little C preprocessor check to
prevent future engineers (including especially future-me) from
thinking that they can change this value without updating the related
code.
- Add GL_RGBA support to hwui's FontRenderer and friends
This also happened to involve some refactoring for convenience and
cleanliness.

Introduce PixelBuffer API to enable PBOs
PBOs (Pixel Buffer Objects) can be used on OpenGL ES 3.0 to perform
asynchronous texture uploads to free up the CPU. This change does not
enable the use of PBOs unless a specific property is set (Adreno drivers
have issues with PBOs at the moment, Mali drivers work just fine.)
This change also cleans up Font/FontRenderer a little bit and improves
performance of drop shadows generations by using memcpy() instead of
a manual byte-by-byte copy.
On GL ES 2.0 devices, or when PBOs are disabled, a PixelBuffer instance
behaves like a simple byte array. The extra APIs introduced for PBOs
(map/unmap and bind/unbind) are pretty much no-ops for CPU pixel
buffers and won't introduce any significant overhead.
This change also fixes a bug with text drop shadows: if the drop
shadow is larger than the max texture size, the renderer would leave
the GL context in a bad state and generate 0x501 errors. This change
simply skips drop shadows if they are too large.

Add a new method for text gamma correction
To select the gamma correction method, adb shell setprop hwui.text_gamma_correction
with one of the following values:
lookup3
lookup
shader3
shader
See Properties.h for more information about these different methods.
You can also control gamma correction using the following properties:
hwui.text_gamma
hwui.text_gamma.black_threshold
hwui.text_gamma.white_threshold

Add shader-based text gamma correction
To enable it, the system property ro.hwui.text_gamma_shader must be
set to true. For testing, DEBUG_FONT_RENDERER_FORCE_SHADER_GAMMA
can be set to 1 in libhwui/Debug.h.

Make glyph cache more flexible
Some GPU architectures could not handle the previous implementation
of our glyph cache. Frequent uploads would cause memory problems in the GPU
and eventually a crash due to these memory issues. The solution is to move to
a system of several, smaller caches instead of one monolythic cache for all
glyphs.

Memory optimizations for libhwui
Bug #5566149
Lazily initialize font renderers
Keep 60% of the texture cache when an app goes to the background
Delete least used font renderer when going to the background
Delete all font renderers on full memory trim

Move all debug flags in a single place.
This change also adds a new memory usage flag. When turned on, the
following is printed after every frame:
D/OpenGLRenderer( 3723): Current memory usage / total memory usage (bytes):
D/OpenGLRenderer( 3723): TextureCache 3766680 / 20971520
D/OpenGLRenderer( 3723): LayerCache 3538944 / 8388608
D/OpenGLRenderer( 3723): GradientCache 135168 / 524288
D/OpenGLRenderer( 3723): PathCache 41180 / 4194304
D/OpenGLRenderer( 3723): TextDropShadowCache 0 / 2097152
D/OpenGLRenderer( 3723): FontRenderer 0 262144 / 262144
D/OpenGLRenderer( 3723): FontRenderer 1 262144 / 262144
D/OpenGLRenderer( 3723): FontRenderer 2 262144 / 262144
D/OpenGLRenderer( 3723): Other:
D/OpenGLRenderer( 3723): FboCache 2 / 12
D/OpenGLRenderer( 3723): PatchCache 31 / 512
D/OpenGLRenderer( 3723): Total memory usage:
D/OpenGLRenderer( 3723): 8268404 bytes, 7.89 MB
This should help tracking possibe memory issues.

Optimize FBO drawing with regions.
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.
