96dpi with sub-pixel anti-alias method

When setting the scaling dpi to <144dpi while the system is using "greyscale"
font anti-alias method, Wine won't anti-alias any font. But using "sub-pixel"
method will make it working.

I have tried adding "+font" into the "WINEDEBUG" env var, and I got a pretty
interesting log saying "0110:trace:font:freetype_get_aa_flags font L"Tahoma"
-11 aa disabled by GASP" (more log info at the attachment)
