CG smoothing implies gamma blit.

There are three distinct attributes controlled by font smoothing,
subpixel converage, fake bolding, and gamma 2 blitting. In macOS 14 the
subpixel coverage was removed but the other two apparently remain. Prior
to this change the code had assumed that the gamma 2 blitting had also
been removed, but this appears not to be the case.
