Merge perspective feature for PDF.

From Skia's repo:

http://code.google.com/p/skia/source/detail?r=11751
Add SkPDFDeviceFlatenner which extends SkPDFDevice to add support
to flatten the path and the text when we have perspective. prepare
to deprecate SkPDFDevice constructor, and route gm and render_pdfs
to use SkDocument::Create pdf interface instead. - controlled by a
flag add comments where we are supposed to flatten other features
(paint, shaders, ... )

Implement perspective for bitmaps in pdf.

PDF: support perspective in simple shaders. (this version does not
work well with tilling)

Fix drawing xfermodes to PDF.

[PDF] Improve complex xfer mode support.

Xfer mode applies only to the shape of the source drawing, not everything in the
clip as in currently implemented.  It's just that the current gm examples draw a
shape that fills the visible layer.

Use nine patch drawing for blurry round rectangles

Cherry pick of https://codereview.chromium.org/52703003/ in Skia.

Add SkRRect::transform.

Much like SkPath::transform, it transforms an SkRRect based on an
SkMatrix. Unlike SkPath::transform, it will fail for matrices that
contain perspective or skewing.

Add ability to ninepatch blurred rounded rectangle

Speed up drawing large blurry round rectangles by converting them to
nine patches.

SkDraw:
Add drawRRect.

SkBitmapDevice:
Call SkDraw::drawRRect instead of converting SkRRect to an SkPath.

SkMaskFilter/SkBlurMaskFilter:
Create a nine patch of a blurred round rect and draw it instead of
drawing the entire thing.

SkPDFDevice:
Override drawRRect to perform the old behavior in
SkBitmapDevice::drawRect.

Override drawRRect in fake SkBitmapDevices.

Recent changes to SkBitmapDevice modified ::drawRRect() to take
an optimized drawing case. Some subclasses of SkBitmapDevice were
depending on the old behavior of calling ::drawPath(). Since they
do not draw, attempting to take the drawing path can cause problems.
For these subclasses, call drawPath() in the subclass.
