Is pfFlux optimized to the case where we know that in each frame each
coordinate and its associated normal will change? Is it true that in this
case all data will be copied down the render pipe (unless PF_APPCULLDRAW
is used)? What about using a pfSwitch, which dynamically cycles through 3
different subgraphs that share their texture maps and texture coordinates
but have their own coordinates and normals. Since pfSwitch is synchronized
automatically, there should be no need to copy any data. All that has to be
done is to increase pfSwitch such that it point to the new subgraph and
update the coordinates and normals.
