5d415079fc Mark drawbitmaprect's large bitmaps as immutable. 
This reduces the peak memory usage of out/Debug/dm --skr --match drawbitmaprect from ~1.6G to ~200M.

I'm not sure how the numbers got so huge to begin with from a 2K x 2K 8888 bitmap (16MB).

a90c680386 Turn on quilt mode in DM. 
- Rename TileGrid -> Quilt to avoid the name overload.
  - Tag all failing GMs with kSkipTiled_Flag.

You may be wondering, do any GMs pass?  Yes, some do!  And that trends towards all of them as we increase --quiltTile.

Two GMs only fail in --quilt mode in 565.  Otherwise all GMs which fail are skipped, and those which don't fail aren't. (The 8888 variants of those two GMs are skipped even though they pass.)

0a5c233e3b Implement bounds traversals for tile and matrix convolution filters. 
Add a new GM that exercises tiled drawing all pixel-moving filters
(and some non-pixel-moving ones) and compares it against non-tiled
drawing of the same filters. Fixing this test revealed that tile and
matrix convolution filters had no onFilterBounds() traversals
(test-driven development FTW). Tile requires (conservatively) the
bounds to include the whole source rect, since it may end up in the
result. Matrix convolution requires the bounds to be offset by the
kernel size and target.

As a first step towards removing SkShader::setLocalMatrix, which will make
SkShader thread-safe, remove calls to setLocalMatrix that happen immediately
after the shader is being created. Instead, pass the matrix into the constructor
or factory method.

5fb2ce38b3 Staged removal of SkPicture-derived classes 
This CL removes the SkPicture-derived classes (with a flag to keeps clients working). In the process it also lightens the recording factory function so it is no longer ref counted).

The only interesting bits are in SkPicture* and Sk*Picture.*

d393b17cf3 Retract SkPicture::kOptimizeForClippedPlayback_RecordingFlag from public API 
This CL sets the stage for retracting the SkPicture::kOptimizeForClippedPlayback_RecordingFlag flag
from the public API (more work needs to be done in Blink & Chrome). In the new world the only way
to set this flag (and thus instantiate an SkPicture-derived
class) is by passing a factory to the SkPictureRecorder class. This is to get all clients always using
factories so that we can then change the factory call used (i.e., so the factory just creates a BBH) and
do away with the SkPicture-derived classes.

This change resized the canvas for some GM cases. It is better to show the visual difference in viewer.html for these cases after the CL applied.

f7efa502d6 Implement intra-frame cacheing in image filters. 
When image filters are processed within Skia, they simply do
a blind recursion. This has the side-effect of turning the
DAG into a tree. I.e., nodes visited more than once during
the traversal will be processed more than once.

This change implements a very simple cacheing scheme: a
cache is created before traversing the DAG, and handed
into the processing traversal. Before recursing into a child
in SkImageFilter::filterImage(), the cache is checked for a
hit, and early-out is performed. Otherwise, the node is
processed, and its result bitmap and location (offset) are
cached, but only if it contains two or more children and
thus will be visited again during the traversal.

Currently, the child count is approximated with the
refcount. This is good enough in most cases (and exactly
correct for the Chrome use case). We could add an exact
child count to the image filter, but this will require
violating the immutability of image filters slightly in
order to bump the child count as nodes are connected. I
leave it up to the reviewer to decide which is better.
