Subject: SUPERNOVA: Removes 'inverse section' case
This code section was converted from the original source, where the
sections are directly drawn to the screen instead of buffered.
If a section > 128 is set as parameter, the function takes the
dimensions of section - 128 and draws this region of section 0 to the
screen, thus restoring it.
It would not make sense loading part of section 0 in seperate Surfaces
especially since kMaxSection is smaller than 128 the else branch is
never entered so removing it doesn't change the programs behavior.
