- Camera translate in camera view, with MMB, works again. Code needs
verification by Martin... it does it different now too.
- Camera rotate in camera view works again. MMB switches to 'trackball',
as formerly. Isn't consistant with other rotate+MMB though...
- rotate camera in cameraview around cursor doesn't 'feedack' anymore
Martin; I only use the TransInfo->persinv[4][4] now, but I think it's
safe to use viewmat and viewinv too?
