2961769ea94f69c191a2dd785b2504666c7292d0 25-Apr-2014 Svetoslav <svetoslavganov@google.com> Adding APIs to render PDF documents.

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.

2e0103eb340822f9d580c1aa8492bae8394b8243 04-Apr-2014 Leon Scroggins III <scroggo@google.com> Remove SkFloatToScalar.

Now that SkScalar is always float (it may someday be double, but
float to double is trivial), remove callers of SkFloatToScalar,
which is deprecated in Skia.

cc11f15f76a62ded3e403cb2bc818c6aa5bf261c 31-Mar-2014 Leon Scroggins <scroggo@google.com> Update to call new Skia APIs.

I816129d49c0118453222916f3c818eccac33663d merges a new version of
Skia that updates various APIs. Call the new ones.

SkBitmap::copyTo now takes an SkColorType instead of an
SkBitmap::Config, so do the conversion with
SkBitmapConfigToColorType or use the enum when it makes sense.

Call SkImageDecoder::decodeSubset instead of (deprecated)

Override SkCanvas::ClipVisitor::clipRRect in ClipCopier.

In Canvas::clip calls, call SkCanvas::isClipEmpty(), which was
previously called inside the clip call, to determine the return value.

For various SkPaint effects, call the new factories (as the constructors
have been made protected).

Implement SkJavaOutputStream::bytesWritten(), overriding a new pure
virtual function on SkWStream.

Update Matrix calls to always return true (since SkMatrix calls no
longer return a value).

Depends on I816129d49c0118453222916f3c818eccac33663d (skia).

These changes are needed due to changes in the Skia API.

Depends on https://googleplex-android-review.git.corp.google.com/#/c/439626/1

Use SkColorType instead of SkBitmap::Config, where possible.
Call SkBitmap::info() instead of deprecated SkBitmap::asImageInfo().
Remove calls to deprecated SkBitmap::getSize64().

Remove the deprecated SK_SCALAR_IS_FIXED path. Leave in an else case for
SK_SCALAR_IS_FLOAT, to allow for eventual SK_SCALAR_IS_DOUBLE path.

Like in BitmapFactory.cpp, use new methods for determining the size of

Use more precise SkScalar_ToInt versions of macros.

Fix bug in macro definition for HB_SurrogateToUcs4.
Use the new name for SkCreateTypefaceForScriptNG.

Replace ScreenshotPixelRef with a Skia pixel ref.

the following authors:

Due to the very large number of internal conflicts, I
have chosen to cherry-pick this change instead
of letting it merge through AOSP because the merge
conflict resolution would be very hard to review.

Commit messages below:

AArch64: Make graphics classes 64-bit compatible

Changes in this patch include

[x] Long is used to store native pointers as they can
be 64-bit.

[x] Some minor changes have been done to conform with
standard JNI practice (e.g. use of jint instead of int
in JNI function prototypes)

[x] AssetAtlasManager is not completely 64-bit compatible
yet. Specifically mAtlasMap member has to be converted
to hold native pointer using long. Added a TODO to
AssetAtlasManager.java to indicate the change required.

AArch64: Use long for pointers in graphics/Camera

For storing pointers, long is used in
android/graphics/Camera class, as native
pointers can be 64-bit.

In addition, some minor changes have been done
to conform with standard JNI practice (e.g. use of
jint instead of int in JNI function prototypes)

768480c2458fda63f5eaab37c03e0671d759c514 26-Jan-2014 Mathieu Chartier <mathieuc@google.com> Fix dest == src bugs in Matrix.cpp.

The main bug was that the AutoJavaFloatArray autoSrc was not passing in
read only. This meant that the destructor overwrote the data which
the autoDst AutoJavaFloatArray had written in it's destructor.
This case only happened if src == dest and the arrays were copies.
Also improved performance by passing in read only a few other places.

d98aa2de9ab18e09c2be1997f41212740f51f6e6 26-Oct-2010 Chet Haase <chet@google.com> DisplayList optimizations and fixes.

We now use a copy of SkPaint objects to avoid having it changed from under us.
We reuse copies that have not changed. We also copy the SkMatrix every time to
avoid the same problem.

27f0b17d853d8bef918c3d869044e50cf3904ee3 22-Oct-2010 Chet Haase <chet@google.com> Fix native resource leak when OpenGL renderer is not being used.

Native resources (bitmaps, matrices, paints, shaders) are shared when display lists
are used, and a refcounting system is in place to take care of disposing when all
clients are finished with them. But the cache where these refcounts are tracked is
not enabled when the Open GL renderer is not being used. This results in the native
destructors not being called, and the resources are leaked.

Simplified the code in ViewGroup for splitting events across Views.
The new code also handles the case where some pointers are dispatched
to the ViewGroup in addition to its children whereas the previous
code would drop some pointers on the floor.
