Introduce PixelBuffer API to enable PBOs
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.

Less aggressive glyphs precaching
The renderer used to pre-cache glyphs at record time. This then changed
to pre-caching at the beginning of every frame. This unfortunately entails
a lot of duplicate work on every frame, which amounts to 0.5 to 1ms in
some stock applications.
This change is somewhere in the middle: pre-caching happens the first
time a DrawTextOp is deferred or every time the screen-space transform
is different from the last pre-caching operation.

Take only the scale params into account to rasterize text
This change extracts the scale parameters of the current transform
to pass then to the font renderer. Rotation and perspective are
applied to the generated mesh inside the vertex shader. This limits
the number of glyphs we have to create in the font cache and thus
reduces memory churn.

Precache glyphs at final raster size
The deferred display lists model now allows us to precache glyphs
at their exact size on screen.
This change also removes debug markers when the renderer defers
and reorders display lists. It also adds a flush event marker.

Support 3D rotations when drawing text
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.

Properly scale text
This change does not apply to drawPosText() and drawTextOnPath() yet.
Prior to this change, glyphs were always rasterized based on the
font size specified in the paint. All transforms were then applied
on the resulting texture. This creates rather ugly results when
text is scaled and/or rotated.
With this change, the font renderer will apply the current transform
matrix to the glyph before they are rasterized. This generates much
better looking results.

Add plumbing for better text scaling
Fonts are now described by a transform matrix. This lead to switching
from a vector to a hashmap. This change therefore adds new comparators
and hash computations to Font.

Don't invalidate all the glyphs when flushing large textures
FontRenderer::flushLargeCaches identifies the large textures used to
cache glyphs and visits all the known fonts to mark their glyphs
invalid if they belong to one of these large textures.
Unfortunately, Font::invalidateTextureCache had a logic error
which would make it mark *all glyphs* as invalid, not matter
what texture they belong to. This means that any large cache
flush would cause all glyphs to be invalidate, thus forcing
the rendering system to recreate them on the next draw.
Font::invalidateTextureCache is supposed to behave this way:
- If the specified cacheTexture is NULL (default value), mark
all glyphs as invalid (see FontRenderer::flushAllAndInvalidate())
- If cacheTexture is *not* NULL, invalidate only the glyphs for
which glyph.cacheTexture == cacheTexture.
The previous condition read:
if (cacheTexture || glyph.cacheTexture == cacheTexture)
This test *always* passes.
