DirectWrite to detect GDI only fonts.
The exist a number of webfonts which have poor hinting which look very
bad with any vertical subsampling. The fonts often rely on drop out
control to avoid zero coverage in the y direction. As a result, any font
with hints but no 'gasp' table is considered to be poorly hinted in this
way, and will not be rendered with vertical subsampling when hinted.
