  [raster] Increase the raster pool density.
  
  This only helps to delay the pool overflow and bisections to larger
  sizes and benefits only very intricate glyphs at reasonable sizes.
  
  * src/raster/ftraster.c (TProfile): Use Int instead of Long or PLong
  when it is sufficient.
  (New_Profile, End_Profuile, Bezier_Up, Sort): Updated accordingly.
