Google optimized the uploadToTexture with GLES3.0+,
This allows us to upload a sub-rectangle of texture,
but this has compliance issue with GLES 2.0.
With OpenGL ES 2.0 we need to copy the bitmap in a
temporary buffer if the stride doesn't match the width,
and then upload entire temporary stripes.

Instead of duplicating internal info about SkShader, inspect the
SkShader installed on the SkPaint.
core/java/android/view/GLES20Canvas.java:
Remove setupModifiers, nResetModifiers, and nSetupShader.
core/jni/android/graphics/Shader.cpp:
Remove calls to create/destroy the (previously) attached SkiaShader.
core/jni/android_view_GLES20Canvas.cpp:
Remove native code for setupShader and resetModifiers.
graphics/java/android/graphics/BitmapShader.java:
graphics/java/android/graphics/ComposeShader.java:
graphics/java/android/graphics/LinearGradient.java:
graphics/java/android/graphics/RadialGradient.java:
graphics/java/android/graphics/Shader.java:
graphics/java/android/graphics/SweepGradient.java:
Remove code keeping track of native SkiaShader.
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/DisplayListOp.h:
Access the SkShader on mPaint.
Remove SetupShaderOp and ResetShaderOp.
libs/hwui/DisplayListRenderer.cpp:
libs/hwui/DisplayListRenderer.h:
Remove resetShader, setupShader, refShader, and mShaderMap.
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.
libs/hwui/SkiaShader.cpp:
libs/hwui/SkiaShader.h:
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.

Bug #7353771
This API can be used when scaling large images down to a small size
to get nicer looking results.

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

Bug #3179882
Resources were freed following garbage collections on a worker thread.
This worker thread had no EGL context, which would cause the renderer
to incorrectly assume that the memory was liberated.

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.

We now use a copy of SkPaint objects to avoid having it changed from under us.
We reuse copies that have not changed. We also copy the SkMatrix every time to
avoid the same problem.

The makefile variable USE_OPENGL_RENDERER must be set to true to compile
libhwui and the related code in the JNI layer.
This change also removes obsolete APIs from Canvas that must not be used
and would be confusing if left in. These APIs were remnants of our first
attempt at an OpenGL renderer for the view hierarchy and had not been
taken out before Android 1.0 was released.

When an app tries to render a bitmap or path larger than the GPU's maximum
texture size, the drawing command is ignored and a warning is logged. This
change also makes texture drawing more robust by catching potential errors
during texture creation.
This change also fixes a crash in the FontRenderer. The destructor would
sometimes try to free an uninitialized array.

This change removes the need for the SortedList and instead just
add a generated id to each FBO stored in the cache. This is an
artificial way to store several FBOs with the same dimensions.
Change-Id: I9638364e9bdc0f2391261937a0c86096f20505bf
This change introduces a new generational cache called GenerationMultiCache
that can store several values with the same key. This can be used to use
multiple layers of the same size at the same time, without recreating them
over and over again.
Change-Id: I425466a20908b862c5f464a0f9e582ec18cbd7ac
The cache is used to draw layers so that a new
texture does not have to be recreated every time
a call to saveLayer() happens.
The FBO cache used a KeyedVector, which is a bad
idea. The cache should be able to store several
FBOs of the same size (this happens a lot during
scrolling with fading edges for instance.) This
will be changed in a future CL.

The texture cache was previously checking the number of stored textures. This was
not very useful as this could easily lead to an abuse of memory. The new cache
instead tracks the total size occupied in RAM by the cached textures. When a new
texture is generated, older textures are kicked out as needed.
