and if legal, returns the new width which will be used to compute a modulated alpha.

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)

- smulbb is only on ARMv5TE and above (p316, ARM Architecture Reference Manual)
- an empty clobber list causes a compiler error with my compiler, gcc-4.3.2

add beforeChild/afterChild methods for parents to wack the canvas before/after
it draws. These are called after the std child-view translate and clip, unlike
beforeChildren/afterChildren

(somewhat) than their scale counterparts, but are also numerically exact for
any size bitmaps. The scale versions, because they operate in a scaled 65535
space, are not always exact for large images (due to SK_Fixed1 / width) loss of
bits

Because the underlying mask extends a pixel to the left and right (or
top and bottom on vertical LCDs), the requested pixel can actaully be
one pixel outside the bounds, thus this assertion is incorrect.
