Sam Lantinga d4b561f472 Fixed bug 5015 - SDL_RenderReadPixels on DirectX 11.1 backend seems to be broken 
Konrad

It appears that I cannot use SDL_RenderReadPixels on a bound framebuffer (SDL_Texture set as render target) as it simply results in gibberish data. However, drawing that framebuffer into the default target (window surface) does render it correctly. Other backends (OpenGL, software, Direct3D) do work fine.

It looks to me like D3D11_RenderReadPixels just gets the general backbuffer and not the current render target and its backbuffer.

Here is the patch which actually fetches the current render target and its underlying ID3D11Resource which is ID3D11Texture2D.

Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting
with README.md

Enjoy!
