Thanks a lot for your work. I didn't include your blue-scale patch yet
because I believe it should be possible to perform the same thing in a
much more pleasant way that doesn't involve calling FT_Set_Char_Size
within the auto-hinter. Be assured that such patch will go into FreeType
once the details are cleared out..

By the way, while your changes increase the quality of most fonts, I have
encountered a few cases where it lowered them. For example, try to display
a waterfall of "Georgia" and "Times New Roman" and see how sizes 16 and 18
are. I'd like to correct this before the 2.1.4 release.

Thanks,
