Preserve dithering for SkImageFilters::Shader
Migrating chromium code to use SkImageFilters::Shader over
SkPaintImageFilter requires dithering to be preserved for its gradient
fills.
I debated always forcing it to true, but dithering was never turned on
for the turbulence filter and it's not necessary for const color shaders
Given that, I opted to just make it a parameter to the filter factory,
which seems okay since we're unlikely to embed dithering into SkShader
itself, it's a shading-related parameter of SkPaint, and if we migrate
to always dithering, then we can remove it.
