frames.c: Remove workaround now that clip_to_screen() works properly

Browse Source 
This code seems to be basically broken. It looks like it tried to clip
the expose area to the screen, but used screen coordinates for the
screen area but frame coordinates for the frame area. So someone tried
to work around this by adding a border around the screen, which made the
broken clipping work most of the time (see bugs below for examples where
it didn't).
Anyway, all of this is gone now.
