bug:14083128
Moves all of the font transform management into
OpenGLRenderer::findBestFontTransform(), and now simply passes down
final rasterization transforms into the FontRenderer.

Instead of duplicating internal info about SkShader, inspect the
SkShader installed on the SkPaint.

libs/hwui/Caches.h:
Include Extensions.h.
libs/hwui/DeferredDisplayList.cpp:
Compare shaders on the paint, instead of on DrawModifiers.
libs/hwui/DisplayList.cpp:
libs/hwui/DisplayList.h:
Remove vector of SkiaShaders.

libs/hwui/FontRenderer.cpp:
Pass SkShader to setupDrawShader and setupDrawShaderUniforms.
libs/hwui/OpenGLRenderer.cpp:
libs/hwui/OpenGLRenderer.h:
Add LayerShader, a class inheriting from SkShader, to mimic the
behavior of SkiaLayerShader. Unlike SkiaLayerShader, it can be set on
the SkPaint so it can be inspected later.
Set a LayerShader instead of a SkiaLayerShader.
setupDrawShader and setupDrawShaderUniforms now inspect an SkShader
passed in.
Inspect SkShader instead of mDrawModifiers.mShader.
Remove resetShader and setupShader.
setupDrawColorUniforms now takes a boolean indicating whether there is
a shader.
Add an inline function for accessing the SkShader on an SkPaint.
In setupDrawBlending(Layer*, bool), do not check the shader (which will
never be set), but do check whether the color filter may change the
alpha (newly fixed behavior).
In setupDrawBlending(SkPaint, ...), check the SkShader and whether the
color filter affects alpha (the latter is new behavior).
libs/hwui/Renderer.h:
Remove pure virtual functions setupShader and resetShader.
libs/hwui/ResourceCache.cpp:
libs/hwui/ResourceCache.h:
Remove functions for refing/unrefing shaders.

Much of this code was redundant and has been removed.
Convert structs into class with nothing but static functions for
calling describe/setupProgram.
libs/hwui/TextureCache.cpp:
libs/hwui/TextureCache.h:
Use the SkPixelRef as the key to the bitmap Lru cache, since shader
inspection will provide a different SkBitmap pointer (though it will
hold the correct SkPixelRef with the correct generation ID).
tests/CanvasCompare/src/com/android/test/hwuicompare/DisplayModifier.java:
tests/CanvasCompare/src/com/android/test/hwuicompare/ResourceModifiers.java:
Update manual test to have more shaders: radial, sweep, compose,
invalid compose.

Once the RS::init failed, go through the original single thread path,
this will avoid blocking the main thread(ANR), but we also should have
some implement in RenderScript component.

I guess we don't want to overwrite the last line in every RGBA glyph
with our one-line texture atlas spacer?

Oops! kBW_Format was omitted from a couple of switch statements,
resulting in glyphs in that format being invisible.

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.

This reduces state changes when we draw 9patches and text together,
which happens *a lot*. Also disable the NV profiling extension by
default since it doesn't play nice with display lists deferrals.
To enable it set debug.hwui.nv_profiling to true.

Merge simple bitmap draw operations and text operations to avoid
issuing individual gl draws for each operation. Merging other ops to
be done eventually.
The methods are different - the bitmap merging generates a single
mesh for reused, unclipped images (esp. repeated images in a listview)
The text approach queries just defers the normal font rendering until
the last drawText in the sequence that can share the same shader.
Patches are sorted and merged, but don't yet have a multiDraw
implementation. For now, the pretending-to-merge gives better sorting
behavior by keeping similar patches together.

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.

This change uses a new OpenGL ES 3.0 feature to upload less data when
the font cache needs to be update. This can result in significant
performance improvements on device with large textures or with locales
that use a lot of glyphs (CJK for instance.)
This change also fixes various unpack alignment issues. The unpack
alignment, as well as the unpack row length, is not texture specific
but a global state that affect all glTex/SubImage2D calls. Some of
them were missing the appropriate glPixelStorei() call. This could
result in corrupted textures.

SystemServer is currently a monolithic class that brings up key system
services. This change is the first phase of refactoring it to be more
configurable. Specifically, it adds a set of on/off switches used to control
startup of individual services. Future plans include finer grained controls
and a more explicit and consistent startup sequence for these services.

Only performs the GL setup steps when at least one glyph is drawn.
This change also skips various draw operations when the specified
paint draws with alpha = 0.

This change moves the mesh buffer from FontRenderer to CacheTexture
to help reduce the number of texture binds and glDraw calls when
drawing text that spans across multiple textures.
Change-Id: I7de574d88313ca3672879ca878c253ff5f131fc1
When several CacheTextures are used to draw text, sort the
draw batches by texture ID to minimize state changes in the
driver.
This change also tweaks the font cache size and renames
a property that was too long to be set using setprop.

If a perspective transform is set on the Canvas, drawText() should
not attempt to rasterize glyphs in screen space. This change uses
the old behavior instead (i.e. rasterize the glyphs at the native
font size and apply the transform on the resulting mesh.)
This change also adds an optimization: empty glyphs (spaces) do
not generate vertices anymore. This saves a lot of vertices in text
heavy applications such as Gmail.
