erased. Callers with a SkIRect can just convert to SkRect.

and improve perspective handling in rest of quad pipeline
This function produces 0, 1, or 2 quads clipped to w > 0, with proper
local coords. To make its signature a little easier to reason about,
I added a simple 'DrawQuad' struct that represents the combination of
device and local coordinates, and edge AA flags. I am open to suggestions
for the name.
GrQuad::bounds() remains perspective aware so that it is always correct.
I updated CropToRect to check for w < 0 and not attempt to crop in that
scenario. Theoretically, we could clip to w = 0 first and then go through
the CropToRect optimization path. However, with the current state of the
GrFillRectOp and GrTextureOp, that made it more annoying to have the bulk
APIs handle the w clipping as well.
So for now, the w plane clipping is entirely the responsibility of the
ops. A benefit of this approach is that GrRenderTargetContext doesn't need
to be modified, and in the case where the clipping produces 2 quads they
are automatically put in the same op w/o going through any batching code.
However, it is becoming clear to me that managing 4 effective code paths
(fill + texture X simple + bulk API) is more maintenance than it's worth.
I added skbug:9869 to work out how to simplify these op creation APIs further,
and if we succeed there, I think it will make applying the W plane clipping
more convenient as well.
For now, since this affects SkiaRenderer on Linux stable, I am pushing
for correctness.

The goal of the verifier framework is to enable opt-in checks of the

comparing the rendered output of a GM against a source-of-truth image,
such as one generated by the CPU backend.
In the short term this can enable coarse-grained sanity checks for a
subset of GMs to catch e.g. egregious rendering bugs. In the longer term
this can provide an SkQP-style suite of tests that can be run across
many/all GMs to provide a vote of confidence in the rendering
correctness of new devices.
