This optimization along with the previous one lets us render an
application like Gmail using only 30% of the number of GL commands
previously required

I don't know who's to blame, SGX or Tegra2 but one of those two GPUs is not
following the OpenGL ES 2.0 spec.

Bug #5706056
A newly introduced optimization relied on the display list renderer
to properly measure text to perform fast clipping. The paint used
to measure text needs to have AA and glyph id encoding set to return
the correct results. Unfortunately these properties were set by
the GL renderer and not by the display list renderer. This change
simply sets the properties in the display list renderer instead.
This change also improves the error message printed out when the
application attempts to use a bitmap larger than the max texture
size.

There was an error in some of the OpenGL layer logic such that we would
occasionally set up a layer for rendering and then not clean up when it was
done. This caused future OpenGL rendering to go into that layer instead of
to the buffers being displayed on the screen, resulting in artifacts including
flashes and displaying of stale content. This happened specifically when
using the wifi settings dialog with the InputMethod keyboard displayed,
but it was probably visible in other situations as well.

Bug #5650514
After invoking a GL functor, libhwui restores a few OpenGL states
including the current FBO. The renderer was however making the
wrong assumption that the FBO to restore to was the base layer
instead of the FBO associated with the current canvas state.

IMPORTANT: this change needs two patches for Harfbuzz:
- one concerning hb_utf16_script_run_prev() which was not returning the correct "previous" script
- one for the "script_properties" table that was missing Arabic code point ranges and declaring
HB_Script_Inherited instead of HB_Script_Arabic
The current change is doing the following:
- pass the correct typeface for Harbuzz shaping (depending on the script of the run)
- offset correctly the glyphIDs returned by Harfbuzz
We need to offset the glyphsID as Harfbuzz will return local glyphIDs (meaning in the
local range of the font used for shapping).
We then cannot use those glyphIDs when we are using a fallback Font (Arabic, Hebrews...)
because the FontRenderer needs glyphIDs in the range of all the Fonts (including the fallbacks)

This change sets textures filtering to GL_NEAREST by default. GL_LINEAR
filtering is only used when textures are transformed with a scale or
a rotation. This helps save a couple of fps on some GPUs.

This method is invoked by TextureView.getBitmap() and failures must be
caught to avoid leaving the GL context in a potentially bad state.

The previous implementation was using glBlendFunc with the parameters
GL_ZERO/GL_ZERO which doesn't work for text, paths and other alpha
sources (anti-aliasing.) The correct implementation is GL_ZERO/
GL_ONE_MINUS_SRC_ALPHA.
