After some experiment, equality function is not enough for
high performance animation. To use native glyph cache efficiently,
need to cache the Font object during font variation animations.
This identifier will be used for the key of the cache.

have any evidence of them currently being used, so should be safe to
remove from the unsupported list.

App such as Chrome create child surfaces and parent them to
surfaces provided by SurfaceView. When we enable the blast
adapter for SurfaceView, the IGBP returned to the app is
created in the client and SurfaceFlinger does not know about it.
When the app creates a child surface and provides the IGBP as the
parent surface identifier, SF fails to validate the IGBP and the
surface is not created. This can be avoid if the client creates the
child surface from the SV SurfaceControl but we still need to
support existing APIs.
To fix this, when we create a Surface from the adapter, pass in
the handle of the Blast SurfaceControl. When calling
ASurfaceControl_createFromWindow, use this handle to identify
the parent.

The recently-built Error Prone checker has found many instances where
we're always paying the cost of StringBuilder concatenation, even in
the typical cases where preconditions are successfully met.
Benchmarks have shown that even when replacing these with varargs
formatter strings, the default case is 20x faster.

Font#equals and Font#hashCode reads bytes in the buffer and end up
with bad performance if we use it as key of HashMap.
To improve them, does following.
- Font#hashCode
Use buffer size as hash. Since we only accept OpenType compliant font
files (invalid font data will be IllegalArgumentException in ctor),
the hash collision due to same file size is unlikely happens.
The ByteBuffer#hashCode includes head position as hashCode but
intentionally exclude them from new hashCode since the head position
is not used by platform include native code.
- Font#equals
The ByteBuffer is frequently duplicated for many reasons, e.g. having
different reading head, etc, but the underlying mmaped memory address
has not changed. Fortunately we have this address in underlying font
object. Compare them as a shortcut of content equality.
With this change, the local benchmark for the Font key-ed HashMap look
up gets faster from 30ms to 4us. (on Pixel 3a)

Tighten up Binder.clearCallingIdentity() usage.
The recently added AndroidFrameworkBinderIdentity Error Prone checker
examines code to ensure that any cleared identities are restored to
avoid obscure security vulnerabilities.
This change is a purely mechanical refactoring that adds the "final"
keyword to the cleared identity to ensure that it's not accidentally
modified before eventually being cleared. Here's the exact command
used to generate this CL:
$ find . -name "*.java" -exec sed -Ei \

This reverts commit fc42a99ea5.
Because we are moving away from a wrapper class to delegate
between SkImageFilter and SkShader and instead adding
RenderEffect on RenderNode, this wrapper implementation
is no longer necessary. There are some behavioral
differences between SkShader and SkImageFilter that
would lead to additional complexity in conversions
between these objects and potential bugs.
To simplify this, RenderEffect will be added
directly to RenderNode to support better
caching of rasterization layers that is necessary
for various visual effects like blur.

TextShaper API provides a primitive text layout result, e.g. what glyph is used etc.
Here is the new APIs and its description
- PositionedGlyphs
This is a native instance backed object that gives layout information to developers.
- GlyphStyle
The glyph style is an object that holds the parameters that will be used for drawing.
This object is a subset of the Paint object for avoiding creating lots of Paint copy.
- TextShaper#shapeText
This does a text shaping and gives TextShaper.Result. This is a native backed primitive
shaping API.
- StyledTextShaper
This is a text shaper for a styled text. This will be the top-level developer facing
API for shaping text.

Add support for submitting buffers in SurfaceView via BLAST using
BlastBufferQueue adapter.
Introduce a new config wm_use_blast_adapter_sv, that is disabled by
default to enable the adapter.
When enabled, the blast SC is created as a child of the main
SurfaceView SC and the main SC is set as a container layer. This layer
will continue to handle position, visibility and transforms while the
blast SC will handle buffer updates via the adapter.
