Subject: Colour blending

Some amount of work went into finding appropriate integer arithmetic
formulae that were reasonably accurate. At this point i've settled for
the incorrect-but-faster version. The better-though-slower formulas
are still there in case i change my mind.

It would help to have an assumption such as, but not limited to, the
surfaces are always going to be fully opaque.
