5e49b497ae Update framework to use M33 Skia. DO NOT MERGE
(These CLs are already in master.)

Bug: 13246311

This cherry-picks 7 CLs:

-----------------------------------------------------------------------

Remove calls to deprecated SkBitmap::setIsOpaque()

setIsOpaque() has been removed from ToT Skia.

Update setters for mIsPremultiplied and hasAlpha to take the
other into consideration.

Merge AssetStream with AssetStreamAdaptor.

Add enums to the constructor for AssetStreamAdaptor to choose the
different behaviors used by the (former) two different classes.

The old clients of AssetStream now get the following features of
AssetStreamAdaptor
- Debugging statements on error.
- The stream is an SkStreamRewindable.
- getLength() returns the correct value, and the old way of getting
  the length (read(NULL, 0)) is no longer implemented, since it is
  no longer used.
- isAtEnd() returns the correct value. ToT Skia makes it pure virtual,
  so some implementation is necessary.

Deprecate Android-specific SkPaint functions.

The following functions were problematic:
 const SkGlyph& getUnicharMetrics(SkUnichar, const SkMatrix*);
 const SkGlyph& getGlyphMetrics(uint16_t, const SkMatrix*);
 const void* findImage(const SkGlyph&, const SkMatrix*);

Replacing them with calls through SkGlyphCache solved a nasty crash
bug, so they have all been deprecated.

pass SkGlyphCache into updateGlyphCache()

Doing so prevents us from double-locking the glyph cache, thereby
effectively locking ourselves out of reusing work that we'd just done.

2d5945e887 Take hinting into account when caching fonts

624234f69b 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.

a4adcf0239 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.

c74f45a334 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.

e3a9b24b5e 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.

9f5dab3fc2 Refactor FontRenderer.cpp
FontRenderer.h defined several classes and structures that now live
in the font/ folder. This will make the code easier to read and
maintain.
