Can you elaborate a bit on what would KX_KetsjiEngine::OnResize() do and
how it would be called?
If you just want a handy function to compute the largest power-of-2
texture size that fits the viewport, there is a fast algorithm in
VideoTexture (look for calcSize()).
I would of course have no problem to port that code to a centralized
function.
