Description Daniel 2016-05-08 21:24:07 UTC 
SDL_RenderReadPixels with SDL_RENDERER_SOFTWARE reads pixels from wrong coordinates.

SW_RenderReadPixels adjusts the rect coordinates according to the viewport. But since this is already done by SDL_RenderReadPixels, the final rect has x2 bigger X and Y.
