[ft] CFF_MAX_CID_FONTS

[Tom Bishop, Wenlin Institute]

Hello FreeTypers,

Does anyone know why CFF_MAX_CID_FONTS (maximum number of sub-fonts in a 
CID-keyed file) is 32 in cfftypes.h? I'm using a font in which fd_index.count 
== 53 and triggers the following error in cffload.h:

      if ( fd_index.count > CFF_MAX_CID_FONTS )
      {
        FT_TRACE0(( "cff_font_load: FD array too large in CID font\n" ));

Changing CFF_MAX_CID_FONTS to 64 seems to solve the problem. I'd like to know 
(1) whether the number 32 is based on a specification, or if it's arbitrary, 
and (2) whether changing it to 64 is liable to cause any problem.

Best wishes,

Tom
