Detect when we no longer have a valid range for chopping due to finite float
precision, and just return a degenerate cubic at the end.

3c9b2a4a0e expand SkShader's flag kConstInY to 16 and 32 variants, allowing a shader
(like gradients) to support predithering. If they do, then they would suppress
kConstInY16, since they no longer are const.

The blitters now check for each flag separately, so we don't have to give up
const-in-Y in the 32bit case, since in that mode we don't care about dithering.

cafc9f9e80 fixes around isOpaque and dithering
- copyTo() now preserves isOpaqueness, and BitmapCopyTest tests it
- bitmap shader doesn't claim to have shadespan16 if dithering is on, since its
  sampler doesn't auto-dither (note that gradients do auto-dither in their
  16bit sampler)
- blitter setup just relies on the shader to report if its 16bit sampler can be
  called (allowing gradients to say yes regardless of dither, but bitmaps to say
  no if dithering is on)

32a4249cbd make a deep copy in CreateCGImageRef if we're 565, but first upscale to 32bit.
this at least draws the right colors, since we're 565 and CG only supports 1555
(unless someone knows how to tell CG we're 565...)

Fix ws in picturerecord

Enable dither in sample gradients, so the 4444 case isn't so ugly

5119bdb952 add shader flag kConstInY_Flag
this signals blitters that the shader will return the same results for a given
x value, independent of y. Useful inside blitRect(), where it can cache the
first call to shadeSpan() and reuse it on all subsequent scans. Works with
(non-rotated) linear-gradients, and Nx1 bitmaps.
