Re: reading pixels from a TARGET texture

thanks, I will try; this brings some questions:

* do you means that the current GL_RenderReadPixels does not work ?

* the doc says "WARNING: This is a very slow operation, and should not
   be used frequently." Is this still the case with your version ?

* Ideally I'd rather use an "official" method. Will these changes be
   included in the official SDL2 ?

S.
