This CL using GPU draws every TextBlob by converting it to a
Slug, flattening the Slug, unflattening the Slug to a dstSlug,
and then uses the dstSlug to draw the TextBlob.
Since only DirectMask sub runs are working I have disabled some
code to all empty sub runs. This will be restored in the final
version.
This adds a compile-time flag to control this behavior:
