Guys, you need to learn about alpha blending. In the simplest terms: a
glyph bitmap is colorless but rather gives you a proportion of brush
and background colors: zeros mean that background is unchanged, 255
means it turns into purely brush color, something in between is a mix of
colors. Then you just apply several layers like this: shade first,
filled body second, outline third.
