A fix and unit test for jagged characters
For tip of tree
Test 1 - half pixel rendering
Adjust the positions of the glyph quads so they never land on a 1/2
pixel position. Having a 1/2 pixel position causes some drivers to
point sample the glyphs poorly because the round differently for
different pixels.
Test 2 - smooth scrolling
Move a textblob very slowly in y to make sure in matches a freshly
constructed textblob.
Fix:
Regen the GrTextBlob if the translation is not by whole pixels.
