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.

The warning is wrong, but the compiler does have a point: generatedHash is always false at that point.

145d1c0fdc Proposed SkCanvas API for preLoading textures to VRAM v2.0
This is an update to (Proposed SkCanvas API for preLoading textures to VRAM - https://codereview.chromium.org/192853002/). It takes into account in-person feedback on the initial proposal. The main feedback was to land this closer to where we will ultimately wind up with the reordered rendering capability (and don't have an SkCanvas entry point (yet)).

When --logPerIters is set and --repeat is great then 2 then bench_pictures will run each test "repeat" times (to generate the correct number of timings) by rendering 5 times.

This CL also adds a swapBuffers in addition to the pre-existing flush calls.

c22d139808 Initial QuadTree implementation
In an effort to find a faster bounding box hierarchy than the R-Tree, a QuadTree has been implemented here.
For now, the QuadTree construction is generally faster than the R-Tree and the queries are a bit slower, so overall, SKP local tests showed QuadTree performance similar to the R-Tree performance.

Tests and bench are included in this cl.

At this point, I'd like to be able to commit this in order to more easily use the bots to test multiple configurations and a larger number of SKPs. The R-Tree BBH is still used by default so this change shouldn't affect chromium.

1b1bcc3cea New API for encoding bitmaps during serialization.
This change gives more flexibility to the implementation of
EncodeBitmap to prefer calling refEncodedData, doing its own
encode, or even doing both and making a decision about which
to use.

The new function signature also allows the implementation to
tell the ordered write buffer whether to store the pixel offset,
in the case where the encoded bitmap represents the larger
bitmap, or to ignore the pixel offset, in the case where the
implementation only encoded the subset that is used.

Requires changes to chromium to use the new function signature.
(https://codereview.chromium.org/15496006/)

SkPicture:
New API for EncodeBitmap.

SkOrderedReadBuffer:
Ifdef'd out addition of reading the offset.

SkOrderedWriteBuffer:
Never call refEncodedData. Allow the user to call that from their
EncodeBitmap function, if desired.
This addresses https://code.google.com/p/skia/issues/detail?id=1239
Add in ifdef'd out code to record the offset.

PictureTest and PictureRenderer:
Implement the new definition of EncodeBitmap. Also update the name
of the function to meet coding style guidelines.

This patch changes the semantics of tileWidth/Height to include the border region, and
uses an offset to take into account the fact that there is no outer border for outer
tiles. This patch also fixes a previous bug where the right column and bottom row were
considered to be included in bounds that are expressed as an SkIRect.

905379a74e In picture rendering tools, draw the entire scaled image.
If --scale is used, limit the size of the image drawn to the
scaled picture size, rather than the original picture size.

08085f808b Change the method for timing individual tiles in bench_pictures.
When timing individual tiles in bench_pictures, keep a timer running
across all repeats, and then take the average. The former method of
timing each iteration separately runs into precision errors on some
platforms.

Running on my Mac Pro with OSX 10.8, the cmsecs for the new method
and the old method are roughly the same when checking the CPU time.
When checking the wall time, the old method often gives me 0ms,
while the new method gives me a larger value. I don't think this
can be entirely attributed to rounding though, since on occasion I
see the old method showing a short time period (.05 - .15ms) while
the new method shows .15ms higher (which is in range for the
difference I'm seeing for other tiles where the old method reports
0ms).

Some other changes:
PictureRenderer::resetState now takes a boolean parameter. If called
with false, it will only do a flush, while if called with true, it
will also call finish.

resetState is now called with true everywhere except in between
iterations of drawing the same tile (when timing individual tiles).

render_pictures_main no longer calls resetState directly, since it
already calls end, which calls resetState.

20bd04e365 Turn on the kUsePathBoundsForClip_RecordingFlag in bench, gm and tools that use class PictureRenderer
Chrome uses this flag for recording to skpicture in order to improve performance.
Therefore, skai benchmarks should run with this flag enabled, and we need 
gm and render_pictures test coverage to validate it.  In gm, the vanilla 
SkPicture test step will still run without the flag to ensure that case still gets test
coverage, while the SkPicture test steps that use rtree and tileGrid will now run with
the flag enabled.

84f548cc9d Flags for render_pictures: verify, clone and writeWholeImage:
1) flag to verify PNGs produced by render_picture that produce the same pixels
as simple renderer.
2) flag to write one single image (in tile we write individual tiles) - this
will help running skdiff also
3) flag to clone the picture before rendering

82ec0b00f3 Allow setting a scaleFactor in bench_pictures (and render_pictures).
In TiledPictureRenderer and CopyTilesRenderer, do a postTranslate so
the translate is not affected by the scale factor.

Likewise, use clipRegion for tiled renderer so it will be
unaffected by the scale factor.

Respect the viewport for record, playbackCreation, and pipe renderers.
