To answer the FIXME, no, we shouldn't force this.  The fullscreen flag implies borderless behavior even though the flag isn't set on the window (in case fullscreen is toggled)

The iOS driver sets the fullscreen and shown flags on the window during creation, so we need the mode code to be aware of that, since none of the other fullscreen/shown code paths get run.
FIXME: Maybe we need a better way of detecting that?

Fixed list loop caused when there are two entries in the list and the one being returned is already at the head.

Fixed SDL applications being killed immediately after being backgrounded, because they were trying to draw while minimized.

Thanks to Martin Gerhardy for the patch!

rename : src/libm/math.h => src/libm/math_libm.h

The draw color affects RenderClear() as well.  (thanks to the feedback form to whoever pointed this out)
