Ok, for anyone else trying to figure this out...  I was able to get SPR working
using the above patch, but it only worked if freetype was built with SPR and
*without* BCI enabled.  In the build of freetype I had with both enabled, SPR
did not work and just reverted to grayscale.

Also, on an unrelated note, I find that the full autohint hinting that Wine
uses by default looks bad.  Here is a patch that forces slight hinting for
anyone interested.  I don't know much about wine code, so no guarantees that
this isn't going to break something.  (What I would really like to see is a
patch that will use fontconfig (local.conf, fonts.conf, etc.) to determine the
hinting on a font by font basis, as well as font replacements.  A little beyond
me at this point though.)
