Bug #5230196

Yes, 75px. Any other font size would work. Don't ask.

e3c26851dc Improve rendering performance on some GPUs 
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.

162a021756 Decouple GLES20RecordingCanvas lifetime from GLES20DisplayList. 
Bug: 5062011

Previously, each GLES20DisplayList would hold onto an instance of
GLES20RecordingCanvas.  In turn, each GLES20RecordingCanvas
held onto an SkWriter with a 16Kb buffer along with several other
objects.  With one display list per view and hundreds of views,
the overhead could add up to a few megabytes.

Ensured that the GLES20RecordingCanvas is reset as soon as
the display list has been constructed, thereby promptly freeing
the 16Kb buffer.

Changed GLES20DisplayList so that it acquires a GLES20RecordingCanvas
from a pool as needed and recycles it when done.

Removed some dead code and cruft related to the construction of
GLES20Canvas objects in general.  Some code was written with the
assumption that the underlying renderer object could change
behind the scenes or might be lazily constructed, but that isn't
actually the case so we can simplify things.

Removed an unnecessary weak reference from GLES20DisplayList
to the View.  It isn't actually used anywhere.

Fixed a bug in GLES20DisplayList where isValid() would return
true while the display list was being recorded.  This is incorrect
because the native display list might not actually exist.  Worse,
even if the native display list does exist, it is stale and
potentially refers to old Bitmaps that have been GC'd (because the
mBitmaps list was cleared when recording started).

f6a63ae3a7 Fix memory leak in OpenGLRenderer. 
When creating a display list, matrices are duplicated locally. They
were however never deleted, thus causing apps to slowly leak memory
(a matrix is about 40 bytes.)

f504a2fa14 Correctly implement the CLEAR xfermode. 
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.
