[fixed for V0.36] Using PNG for Blue Haze = Crash

[Sophia]

RTC crashed whilst trying to use a png with alpha channels to replace the graphic for a blue haze. (Which would've looked quite nice!)

Error:
an access violation exception.

Stack Dump:
RTCMediaGraphics.SurfaceFill(pointer 0x00DE02F0, int 1);
RTC.ProgStateInDungeon();
RTC.DoFrame(int 50);
RTC.WinMain();

I can send the offending image if it has anything to do with it.
