Did I read that post correctly? I think it supports my choice of bitmaps
over vectors for the future.

I have heard that the key to performance is the number of times you need to
render your vectors to bitmaps. There are certain things (like zoom
effects) that you don't think twice about using in vector rendering that
kill you when trying to get to the GPU. I think I was told that if you can
design your visuals as a set of fixed size visuals (which I guess games
often do) then you get the benefits of GPU. Then the question is, if your
visuals are fixed size, why not transcode them to bitmaps at compile time
instead of run time?
