[Freetype] Saving RAM memory - using the raster pool and more

[Nir Rostoker]

Hi !
As I understand the raster_pool need minimum of 4k memory .....

I have a few questions regarding it:

1. if I use less than 4k, will it influence severely the performance ? how
does 4k as a limit was decided ?

2. I start thinking of using the memory which was allocated for the pool as
my target bitmap, I tried doing it, but I get all the     
    time exceptions. Do you know if on the stage I need the bitmap, the
render pool is still used ? Does anyone tried it ?

3. Last question: I have noticed that the difference in RAM needed by the
Load_Glyph() function changes dramatically   
   when using different font file (*.ttf), even though the stream was
already allocated before (which is the main memory       
   part that depends on a specific font file). 
   Does anyone know what big allocations the Load_Glyph()  function does ?
Can I prevent some of it ?
