[ft] Management of resources for bitmap

[Jacques Beaumont]

First congratulation to the developers. The Free type
  library is just a wonderful resource.

   I'd like to manage memory in glyph to bitmap conversion
   in order to optimize performance. I may miss something but 
   I could not find a routine to do that.

   Here is the context. 
   I am developing a graphic front end interface which requires annotation,
   essentially small string <128 chars, that I send to the graphic engine
   through the texture buffer.

   Now in order to preserve flexibility e.g. rendering fonts of different size 
and color
   I'd like to proceed this way. Load in memory the font file, scan my strings, 
render
   them in a memory buffer large enough to accomodate any given string and then 
   load the rendered string in the texture buffer for later placement on 
graphics.

    I can do all this, but I cannot manage memory resources for bitmap. The 
FT_Render_Glyph
    routine allocates memory for each bit map and does not let me assign my own 
resources.
    the FT_Outline_Render allows me to memory management, but I could never get 
it to work well
    when I mix different types of fonts and size (need for 
subscript/superscript and mixing greek and latin
    letters). I'd like to use the render used by FT_Render_Glyph and manage the 
resources myself

    Any suggestions??



Sincerely,
Jacques
