* @values:
* FT_GASP_NO_TABLE ::
* this special value means that there is no GASP table

* do
*
* FT_GASP_DO_GRIDFIT ::
* indicates that grid-fitting/hinting should be
* performed at the specified ppem. This *really*
* means TrueType bytecode interpretation
*
* FT_GASP_DO_GRAY ::
* indicates that anti-aliased rendering should be
* performed at the specified ppem
*
* FT_GASP_SYMMETRIC_SMOOTHING ::
* indicates that smoothing along multiple axis
* must be used with ClearType.
*
* FT_GASP_SYMMETRIC_GRIDFIT ::
* indicates that grid-fitting must be used with
* ClearType's symmetric smoothing
