Patch for SDL_rotozoom.c

SDL Development

SDL_rotozoom.c allocates surfaces without checking for success. This is
the patch against version 2.0.9:

619a620,621

if (rz_src == NULL)
return NULL;
671a674,675
if (rz_dst == NULL)
return NULL;
676a681,682
if (rz_dst == NULL)
return NULL;
741a748,749
if (rz_dst == NULL)
return NULL;
746a755,756
if (rz_dst == NULL)
return NULL;
865a876,877
if (rz_src == NULL)
return NULL;
885a898,899
if (rz_dst == NULL)
return NULL;
890a905,906
if (rz_dst == NULL)
return NULL;

Oh, I also wanted to thank A. Schiffler for his attempt in obfuscating
the actual resize function (zoomSurfaceRGBA). I had to make a little
modification to it (blit to a SDL_Rect instead of the full image) and I
found easier to rewrite it from scratch. Good job. :(–

Thanks for the patch…

Can send us your full version???

It’s work in progress. I’ll make you know when it’s ready… however
it’s the infamous SDL_BlitResize function.–
