[sdljava-users] Aaaaaaargh...

[Rainer K. <ar...@gm...>]

I've been checking my code over and over again for a bug (or rather
undocumented feature?) which is actually in the native binding :/
This costed me hours and hours.

Why isn't this documented?  SDLBlitSurface doesn't behave as it should
due to those changes below.

   int SWIG_SDL_BlitSurface_FAST(SDL_Surface * src, int sX, int sY, int
sWidth, int sHeight, SDL_Surface *dst, int dX, int dY, int dWidth, int
dHeight) {
     srcBlitRect.x = (sX > -1 ? sX : 0);
     srcBlitRect.y = (sY > -1 ? sY : 0);
     srcBlitRect.w = (sWidth > -1 ? sWidth : 0);
     srcBlitRect.h = (sHeight > -1 ? sHeight : 0);

     dstBlitRect.x = (dX > -1 ? dX : 0);
     dstBlitRect.y = (dY > -1 ? dY : 0);
     dstBlitRect.w = (dWidth > -1 ? dWidth : 0);
     dstBlitRect.h = (dHeight > -1 ? dHeight: 0);

     return SDL_BlitSurface(src, &srcBlitRect, dst, &dstBlitRect);
   }

Positions _CAN_ be negative.  Otherwise how are you supposed to move a
sprite or image outside of the screen if it is nailed to position 0?

     srcBlitRect.x = sX;
     srcBlitRect.y = sY;
     srcBlitRect.w = (sWidth > -1 ? sWidth : 0);
     srcBlitRect.h = (sHeight > -1 ? sHeight : 0);

     dstBlitRect.x = dX;
     dstBlitRect.y = dY;
     dstBlitRect.w = (dWidth > -1 ? dWidth : 0);
     dstBlitRect.h = (dHeight > -1 ? dHeight: 0);
