It is safe if you do the necessary bookkeeping.  Reload all textures in
video memory.  Don't assume that you will get the same pixel format.  If you
have a pointer to the video surface stored somewhere, reset it.  Refresh the
video surface.

It isn't supposed to require the bookkeeping tasks listed above.
