Ok, it looks like the rootless server basically does fbComposite, but
accelerates it if (dstMask == FB_ALLONES && pDst->pDrawable->bitsPerPixel == 32 &&
        		width * height > rootless_CompositePixels_threshold &&
	        	SCREENREC(pDst->pDrawable->pScreen)->imp->CompositePixels). 
So how about instead of duplicating fbComposite, we move the check into
the begining of SafeAlphaComposite do the acceleration if appropriate
and otherwise call fbComposite.

If this sounds like a good approach I'll try and put together a patch
when I get the time.
