If your scene is so complex that the vectors can't be re-rendered as
fast as you can spin the wheel, then what are you going to do?
Have you seen what evince does on a scale change? It first scales the
previously rendered rasterization and then when its complete, replaces
it with a new rasterization at the final scale. That kind of approach
should work quite well with mad mouse-wheel spinning, (particularly
since the scaling-of-raster part should be something that's fully
accelerated by the video hardware).
