26e0e587f7 SkImage_Raster's pixels are always immutable.
To make this work, we tag their pixelrefs as temporarily immutable, allowing
ourselves to restore the pixels to mutability only when the image drops away.

This should allow us to wobble back and forth between writing to the Surface
and reading from the Image without a COW, with the Surface seeing mutable
pixels and the Image seeing immutable pixels.

The big idea is, Image doesn't need forever-immutable pixels, it just needs
pixels that are immutable as long as it's alive.

9a5d1ab54d Make peekPixels() usable with raster surface snapshots
SkSurface_Raster snapshots do not lock their backing bitmaps when the
pixel ref is shared - they only lock on deep-copy.

But since for raster surfaces the pixels are always in memory, I think
it would be OK to also lock in the former case.

This allows for optimized (zero-copy) reads of raster surface snapshot
data.

9a53fd7c41 Begin kLegacyFontHost_InitType cleanup
This CL starts the process of pushing kLegacyFontHost_InitType-type SkSurfaceProps up the call stack and out of Skia. It:

 Gets rid of the default SkBaseDevice ctor. This means everyone has to always hand an explicit SkSurfaceProps to it.

 It makes public the SkBitmapDevice creation methods that require SkSurfaceProps.

 Removes (in Skia's code base) all SkBitmapDevice ctor calls w/o SkSurfaceProps.

 Makes the "recording" canvases (e.g., pdf, svg, xps) explicitly not use kLegacyFontHost_InitType.

 Replicates the creating canvas/device's flags on saveLayer devices

a9d9a39238 Read pixels in BGRA non-premul mode in few tests
The tests assert on Sk_ColorGREEN, which is in BRGA non-premul. Read the
pixels in same color format.

Currently the tests pass on all platforms because GREEN is fully opaque
and the component stays in the same place both on BGRA and
RGBA. However, hypothetically somebody could copy-paste the assertion
for further tests but use, say, RED. This creates latent error that is
only visible on some platforms like mac.

a9baa652bb Revert of Add image as a draw type that can be filtered (patchset #4 id:60001 of https://codereview.chromium.org/960783003/)
Reason for revert:
Fails on mac for some reason.
Also is a bit wrong, but this should not be reason for the failure..

Add image as a draw type that can be filtered.

This is needed when SkImage is added as an object to be drawn so that
the draw is forwarded to SkBaseDevice. This would be used in making
filters use SkImages.
