Fixed bug 3349 - GLES2_RenderReadPixels doesn't use target texture format

Browse source 
Simon Hug

The OpenGL ES 2 renderer does not check the target texture format when using SDL_RenderReadPixels and just always uses ABGR8888. This can result in swapped or wrong colors.

The attached patch adds a check and selects the target texture format, if a texture is set as the target.
