Hi again,

Actually, it's probably better to have these functions within the rasterizer,
simply because they're critical to its performance, and can be inlined by an
optimizing compiler..

this wouldn't be the case if we were using functions from another module.
Besides, I like the idea of the rasterizers being self-contained..

Please don't do that !! The reason why the rasterizer uses as few FreeType
types as possible directly is to allow easier experimentation. For example,
it can be useful to change TPoint to:

    double  x;
    doubly  y;

when testing new algorithms..
