Use CopyRect to copy each vertical line in the 'mirror' image and flip it horizontally.
I might have some code somewhere...
[edit] Found it. Its a bit untidy, and not commented as it was never written for anybody else to use, but its not difficult to understand.
XX, YY, W and H are the X/Y coords, width and height of the rear view mirror image (which is drawn directly onto the screen with RenderWorld).
The rear view mirror image is then grabbed to an imagebuffer (tmp), flipped horizontally in the For/Next loop into imagebuffer tmp2, and then pasted back to its original position (XX,YY). Finally, the two temporary Imagebuffers are freed.
