Re: filling area by color atack safety

im not quite sure what you do here.. pass the structure? in fact
the thing you name context you may not pass at all just make is
standalone static variables becouse they/it is the same for whole
"branch" (given recursive branch of recolorisation)
 
something like
 
int old_color = 0xff0000;
int new_color = 0x00ff00;
 
void RecolorizePixelAndAdjacentPixels(int x, int y)
{
   //...
}
