draft2_bugs_41639

I have attached a second patch set draft.

This is also a problem in Linux. It just seemed to stand out in MacOS(builtin
Tahoma) XQuartz2.7.11 Freetype2.7(turned off subpixel).

- v40 legacy font problem(Tahoma, Arial, Courier New, ...).
- v35 cleartype supported font problem(Consolas, ...)

To avoid both problems, I use the gasp table version. This idea is inspired by
the following documentation.

Note that ‘Gray ClearType’ is essentially the same as v1.6's grayscale
rendering. However, the GETINFO instruction handles it differently: v1.6
returns bit 12 (hinting for grayscale), while v2.1 returns bits 13 (hinting for
ClearType), 18 (symmetrical smoothing), and 19 (Gray ClearType). Also, this
mode respects bits 2 and 3 for the version 1 gasp table exclusively (like Color
ClearType), while v1.6 only respects the values of version 0 (bits 0 and 1).

Please test. You won't feel much different from draft1 without fonts like
Consolas. That is the right result.
