RE: [Freetype] Freetype is very slow at opening large Postscript Asian fonts...

[Pedriana, Paul]

So the new loop withing PS_Table_Add (from psobjs.c) could look like
this:


   FT_Error  PS_Table_Add( PS_Table*  table,
                           FT_Int     index,
                           void*      object,
                           FT_Int     length )
   {
      .
      .
      .
      while ( new_size < table->cursor + length )
      {
         /* Increase size by 25% and then round up to */
         /* nearest multiple of 1024.                 */
         new_size = new_size * 5 / 4;
         new_size = (new_size + 1023) & -1024;
      }
      .
      .
      .
   }

I would like to suggest new_size becomes new_size * 5/4 rounded up to
the next multiple of 1024.  This will have good behaviour for small
fonts (by going up by 1KB for small tables that are beneath 4KB) while
at the same time providing the exponential behaviour that you're after.
