Expand the sweep gradient definition to include a color stop angular range ([0, 360] by default).
Color stop positions in [0,1] are mapped to this range, and drawing outside is controlled by a
tile mode param.
This is closer to the CSS gradients spec and allows us to use fewer color stops in Blink conic
gradients.
Impl-wise, the remapping is effected after t calculation, and before tiling.

Gaussian blur filter will interpolate value by using out of bounds
coords, which is 0. This makes it appears darker near the bounds in the
blurred images. There are two issues: 1) when downsampling and
upsampling, we should use GrTextureDomainEffect kClamp_Mode to clamp
the texture coords to the bounds; 2) during Gaussian blur, we need to
clamp to texture bounds.

SkClipOp.h & SkPictureFlat.h
Invalid SkClipOps were getting through - the question here is where (for a class enum) is a good place to put the k*Mask definition.
SkPath1DPathEffect
NaNs were getting past.
SkBlurMaskFilter
Assert wasn't necessary since we whacked the flag on the next line.

It has been incorrectly interpreting its SkColor as sRGB all the time. Now, we plumb through the destintation color space and some scratch space, letting it decide how to interpret its SkColor later when it knows about the dst color space. The scratch space is blitter scoped, which lets this be thread safe (this is much like SkShader::Context).
This only corrects the gamma transformation for now. I've kept my previous TODO about gamut transformation. Everything assumes sRGB gamut for now.
Shaders will get the same treatement in this pipeline.

This breaks the color filter down into a couple logical steps:
- go to unpremul
- apply the 4x5 matrix
- clamp to [0,1]
- go to premul
Because we already have handy premul clamp stages, we swap the order of clamp and premul. This is lossless.
While adding our stages to the pipeline, we analyze the matrix to see if we can skip any steps:
- we can skip unpremul if the shader is opaque (alphas are all 1 ~~~> we're already unpremul);
- we can skip the premul back if the color filter always produces opaque (here, are the inputs opaque and do we keep them that way, but we could also check for an explicit 0 0 0 0 1 alpha row);
- we can skip the clamp_0 if the matrix can never produce a value less than 0;
- we can skip the clamp_1 if the matrix can never produce a value greater than 1.
The only thing that should seem missing is per-pixel alpha checks. We don't do those here, but instead make up for it by operating on 4-8 pixels at a time.
We don't split the 4x5 matrix into a 4x4 and 1x4 translate. We could, but when we have FMA (new x86, all ARMv8) we might as well work the translate for free into the FMAs.
This makes gm/fadefilter.cpp draw differently in sRGB and F16 modes, bringing them in line with the GPU sRGB and GPU f16 configs. It's unclear to me what was wrong with the old CPU implementation.

After getting discouraged by the non-separable xfermodes, I decided to look at filling out the color filters instead. This one's nice and easy.
There's only 1 GM that exercises this color filter, and it's drawing noticeably lighter now in f16 and sRGB configs. 565 is unchanged. This makes me think the diffs are due to lost precision in the previous method, which was going through the default fallback to 8888 filterSpan().
I double checked: the f16 config now draws nearly identically to the gpuf16 config. It used to be quite different.

Many places that construct one are explicitly specifying opaque white or
transparent black, which we can assume (based on the semantics of the
operation) should remain (0,0,0,0) or (1,1,1,1), so that's simple.
In other cases, we convert our source color to destination space.
One wrinkle is tht SkColorFilter now needs to know the destination color
space, due to SkModeColorFilter.

Added gradient shader factories that take SkColor4f + SkColorSpace.
Modified Descriptor to only store SkColor4f + SkColorSpace.
Existing factories make use of helper code to convert SkColor and
forward to the new factories.
Bumped SKP version to handle new gradient serialization format.
I was toying with using half-float when serializing SkColor4f,
despite my aggressive packing of flags, this format is significantly
bigger.
Also added GM to use 4f factories. This GM should (and does)
look identical to the existing gradients GM.
