[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.
