Call blitFatAntiRect to avoid overhead in MaskAdditiveBlitter
This results in 25% (720ns vs 560ns) speedup for
path_fill_small_rect bench in 8888 config. Some skps have a lot of stroked
horizontal/vertical lines (e.g., bar charts) so this improvement could
have a great impact there. For example, cereal converts Microsoft word docx
to PNGs on server and the sample docx has a big bar chart. That inspired
this improvement.
