Sam Lantinga de3d381cb6 Fixed bug 2685 - SDL_RenderReadPixels() doesn't work with offscreen targets 
Andreas Falkenhahn

SDL_RenderReadPixels() doesn't seem to work when trying to read pixels from a texture that has been created using SDL_TEXTUREACCESS_TARGET and has been selected as the render target using SDL_SetRenderTarget().

I am attaching a small program that demonstrates the issue. I get the following result here:

READ PIXEL RETURN: 0 --- COLOR CHECK: ff000000

But it should be:

READ PIXEL RETURN: 0 --- COLOR CHECK: ffff0000

Tested with SDL 2.0.3 on Windows 7.
