We've been seeding the initial values of our registers to x+0.5,y+0.5,
1,0, 0,0,0,0 (useful values for shaders to start with) in all pipelines.
This CL changes that to do so only when blitting, and only when we have
a shader.
The nicest part of this change is that SkRasterPipeline itself no longer
needs to have a concept of y, or what x means. It just marches x
through [x,x+n), and the blitter handles y and layers the meaning of
"dst x coordinate" onto x.
This ought to make SkSplicer a little easier to work with too.
dm --src gm --config f16 srgb 565 all draws the same.

Previously, non-AA quad edges only have an accuracy about 1/2 pixel
(while the AA quad edges have an accuracy about 1/8 pixel). Now, we
increase non-AA quad edges' accuracy to 1/8 pixel as well.
The difference is very significant for rotating non-AA filled circles.
For example, run `./out/Debug/SampleApp --slide GM:fillcircle` with AA
turned off (by pressing b).
The benchmark added reveals that increasing quad accuracy from 1/2 to
1/8 doesn't affect the performance significantly. The following is the

- move bytesWritten calculation to query the tail, allowing write() to be faster since it doesn't have to update anything extra per-write.
- enforce that all blocks are multiple-of-4 bytes big
- update the minimum block size to 4K
Before: 30ms
After: 23ms for non-4-bytes writes
13ms for 4-bytes writes

It's pretty easy to start with sound premultiplied linear floats, pack those to sRGB encoded bytes, then read them back to linear floats and find them not quite premultiplied, with a color channel just a smidge greater than the alpha channel. This can happen basically any time we have different transfer functions for alpha and colors... sRGB being the only one we draw into.
This is an annoying problem with no known good solution. So apply the clamp hammer.
These new calls on SkRasterPipeline should make it impossible to get wrong.
