Cache the blended background in a surface, so that the blending only needs

to be made once, instead of whenever the console is redrawn. (This is the
same trick as the About dialog uses.)

It should speed up the drawing quite a bit, though it's not particularly
noticeable on the computer I'm using at the moment, so I can't say for
sure.
