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.

(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.

- 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)

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.

pattern: the receiver will call ref() if it chooses when passed to a constructor
or setter, so the caller must balance its ownership itself. This matches how all
other refcnt objects are handled.
