Moves method to get GrBackendFormat from GrBackendTexture from GrCaps
to GrBackendTexture so that a GrContext is not required.
Uses kUnknown_GrPixelConfig as failure return from GrCaps functions
rather than an GrPixelConfig* out param and bool result.
Having the texture type be part of GrBackendFormat made removing the
GrCaps function that goes from GrBackendRenderTarget to GrPixelConfig
awkward so that was left alone for now.

This separates the existing convexity logic into
two passes. The first pass detects concavity by
counting the changes in direction.
The second pass computes the cross product to
see that all angles bend in the same direction, and
computes the dot product to see if the angle
doubles back on itself.
The second pass treats axis-aligned vectors
separately, and computes the dot and cross products
by comparing point values; it does not use arithmetic
to determine convexity, so it works with all finite
values.
A compile time switch enables returning concave
for co-linear diagonal points:
If successive points are not axis-aligned, and
those points are co-linear along a diagonal;
the path is treated as concave. This is conservative
but avoids paths that change convexity when the
are translated or scaled, since transforming the
path may cause the midpoint to shift to either
side of a line formed by the endpoints.
The compile time switch is set so that co-linear
diagonal points do not affect convexity. Note that
this permits shapes formerly considered concave, such
as stroked lines with round caps, to become convex;
this accounts for many of the GM differences.
A path may double back on itself and be convex;
for instance, a path containing a single line.
Path may have multiple initial moveTo verbs, or
trailing moveTo verbs, and still evaluate as convex.
A separate entry point, SkPathPriv::IsConvex()
allows passing an array of points instead of a path.
A legacy define has been checked into Chrome to
use the old code until layout tests have been
rebaselined.

This fixes a crash we saw when we switch vulkan copies as draws to creating
their own secondary command buffer. The crash came from the perf blendmode
tests when using an advanced blend mode. They would do 1000 draws which forced
us into creating 2000 command buffers (since the dst copies and the normal draws
each used them). I tested without the copies as draws change and just increasing
the total number of draws we do and was able to repro the crash.
Besides fixing the above OOM crash, I am also seeing a 5-10% perf gain on the
blendmode micro benches which is nice

Zero-initialize the pixel buffer that wuffs uses inside the frame rect.
If the encoded image is incomplete, we will swizzle this memory into the
destination, so this prevents swizzling uninitialized memory.
In addition, zero-initialize the client's memory if the above buffer
will not fill it, and if the frame is independent.
Move decodeFrameConfig into onStartIncrementalDecode. This makes it
clear that we haven't begun decoding the pixels so rowsDecoded is
irrelevant. Update the documentation for onStartIncrementalDecode to
make it clear that it can be called more than once (and when to do so).
If a frame is incomplete and depends on prior frames, do not blend it.
This will overwrite pixels from the prior frames without a way to undo.
Current clients only want to show incomplete images for the first frame
anyway.
Add some debugging information to Codec_partialAnim test, including
writing out pngs when failing the test.

In theory, a convex shape is still convex if transformed by an affine
matrix. However, SkPath segments are specified using floats, and attributes
like collinearity can break under some transforms due to finite precision.
Computing convexity is non-trivial, so there is value in SkPath caching this
calculation. Convexity is useful, as both the CPU and GPU backends can draw
convex shapes faster than non-convex.
To balance these two (fragile float math and value of caching convexity),
this CL invalidates this cached state if the transform could change convexity.
In the general case, it is assumed that convexity could change. Special cases
where it is safe to keep the cached state after transform are:
- identity transform
- scale/translate transform if the path is known to be axis-aligned
All other combinations invalidate the cached state, forcing it to be
recomputed.
"axis-aligned" means the segments in the path are all axis-aligned, horizontal
or vertical (e.g. a rect or rrect)
