What I'd like to end up with is a function that uses rotozoom to rotate a surface about it's own center or about any point for that matter... i.e.

void rotate(SDL_Surface* src, int px, int py, int angle){
}

Because as it stands at the moment if the original x,y values are held constant and the sprite is rotated in the same spot it appears to move left and right unnaturally. Rotation about a pivot inside the sprite is what im looking for. Thanks!
