On modern versions of Android running in AOT mode
FloatMath is slower than Math. Calls to Math.sqrt(),
etc. are replaced by intrinsics which can be as small
as a single CPU opcode.
When running in interpreted mode the new
implementation is unfortunately slower, but I'm
judging this acceptable and likely to be improved
over time. This change saves a small amount of native
code.
Example timings:
Mako AOSP AOT:
Method: Original / New / Direct call to Math
ceil: 596ns / 146.ns / 111ns
sqrt: 694ns / 56ns / 25ns
Mako AOSP interpreted:
Method: Original / New / Direct call to Math
ceil: 1900ns / 2307ns / 1485ns
sqrt: 1998ns / 2603ns / 1788ns
Other calls Mako AOT:
Method: Original / New
cos: 635ns / 270ns
exp: 566ns / 324ns
floor: 604ns / 150ns
hypot: 631ns / 232ns
pow: 936ns / 643ns
sin: 641ns / 299ns
The advice to use Math directly, in preference to
FloatMath, is still good. FloatMath will be deprecated
separately.

A user may request a subset of the document's pages to be printed.
In this case the expectation is that the resulting document does
not include not selected pages. While print serivices can do the
trimming themselves or the printer may do so, moving, potantually
many, redundant pages is inefficient. The real problem is when
saving to a PDF file where the saved file must not have the pages
the user did not select. This change adds shredding of undesired
pages from the PDF before saving it or passing it to a print service.

The idea is that extra paint parameters that only affect text layout
(not rendering) will go in android.Paint instead of going into
SkPaintOptionsAndroid. We will eventually move those out of SkPaint
too.
This is currently implemented in PaintImpl.cpp. Will be renamed when
current Paint.cpp that has JNI bits is moved to android_graphics_Paint.cpp.

This introduces Canvas.h which is a pure virtual interface that
is intended to be used by both Skia and HWUI implementation. To help
stage this transition this CL only introduces the interface and Skia
implementation. The interface is not intended to be final and will
undoubtedly go through iterations in both style and location as we
look to introduce the HWUI implementation.

This patch switches all text layout operations to use Minikin, removes
the USE_MINIKIN #ifdef, and deletes some of the code that was only used
in the old TextLayout path (although some more refactoring remains).

a camera HAL version lower than CAMERA_MODULE_API_VERSION_2_0.
This CL includes support for:
- N-way preview output streams
- N-way jpeg output streams
- CameraDevice emulation at the binder interface
- Basic camera metadata querying in the CameraManager

We need to render PDF documents for two main use cases. First,
for print preview. Second, for resterizing the PDF document by
a print service before passing it to a printer which does not
natively support PDF (most consumer ones).
Adding PDF rendering APIs improves guarantees for print quality
as the same library is used for preview and rasterization. Also
print vendors do not have to license third-party rendering engines.
Last but not least as the platform uses PDF as its main print
format it should also be able to natively render it.

This is the current state of the Minikin integration. All changes are
hidden behind USE_MINIKIN #ifdef, so it should be safe to apply. To
play with the Minikin branch, set this in your BoardConfig.mk .
This change also merges in 64-bit changes that were happenening in
parallel.
