Fixes crash of methods when NULL was used as a
(valid) parameter for a nio.buffer argument.

This implementation adds a drawGeneralText() method to the OpenGL
Renderer, which supports both a global x, y position, an array of
individual glyph positions, and also a length parameter (which enables
drawing of underline and strikethrough. It also adds the method to the
display list (with marshalling and unmarshalling).
With this change, the existing drawText() method is removed entirely, as
it's subsumed by the new method. It's easy enough to revert to the old
functionality if needed by passing in a NULL positions array.

this adds correct versions of the broken GLES20 methods
glGetShaderSource, glGetActiveAttrib and glGetActiveUniform.
the old functions are still there and need to be @hide later.

The mark positioning changes increase the number of bytes needed per
glyph from 6 to 14. This patch compensates by allocating more total
memory for the text layout cache.

I meant to log certain debug values only when DEBUG_GLYPHS was set, but
I used #ifdef instead of #if (when it's not set, it's 0, rather than
undefined).

This patch implements glyph positioning in the Skia-based renderer. Note
that it depends on a fix for bug 6833339 being in place (correct
calculation of advance widths under skew and scale transforms),
otherwise there will be regressions.
Careful attention was paid to correct results in a wide variety of
conditions: alignments, text decorations, scale, skew, etc. Many of
these are exercised in the test app attached to bug 6833339.
Note that this patch also changes slightly the way that the total
advance is calculated - the running is accumulated and passed through to
computeRunValues(), so that the x positions of each glyph can be set
according to the total advance of all glyphs (in all runs) appearing
before (plus, of course, the offset for mark positioning).
After committing this patch, text rendering will no longer match between
the software and hardware rendering cases. Implementing positioning in
the hardware renderer will resolve that, and fully implement bug 5443796.

Contains the updated OpenGL bindings generated by glgen.
Fixes a bug with methods that have more then one nio buffer argument.

Before this change, changing a View's opacity would not be reflected
by hardware layers. This could cause layers to retain their previous
opacity.

There were a number of extraneous typeface pointers, one per
language, in TextLayoutCache. Removing these makes adding additional
supported fonts easier. This checkin now properly
unrefs typefaces returned by SkCreateTypefaceForScript. Additionally,
all harfbuzz shaped fonts (with exceptions Greek, Cyrillic, Hangul)
should call SkCreateTypefaceForScript.

If an app used a GIF file in the wrong density bucket, the auto-scaling

In AudioRecord::getMinFrameCount() and AudioSystem::getInputBufferSize(),
input parameter is channel mask instead of channel count.

Harfbuzz apparently requires the offset array to be initialized to zero,
otherwise it can report corrupt glyph positions. This change also
contains a small amount of refactoring to avoid code duplication.

Some of the logging lines referred to the "path" variable which no
longer exists. We log the Harfbuzz script instead, which hopefully
provides enough context.
This change only affects debug builds, but we will want to be working
intensively in this space.

Fonts can be marked with elegant or compact in fallback_fonts.xml.
Webkit uses elegant fonts, Textview uses compact fonts (the default),
unmarked fonts are used by both.

A code cleanup inadvertently changed the semantics of the function,
causing it to return immediately when the first character is mirrored.
This causes CTS test breakage (in
android.text.cts.AndroidCharacterTest). This change restores the earlier
behavior and causes the test to pass.
