Re: SDL on wide gamut

Hi,

SDL_Surface, and thus all unaccelerated rendering, is limited to 
8bit/channel. This also makes it hard(er) to create a SDL_Texture with 
more than 8bit/chan, but there should probably be a way to do
  SDL_CreateTexture(renderer, SDL_PIXELFORMAT_ARGB2101010, ...)
and fill in the pixel data yourself (with SDL_UpdateTexture()),
but I don't know if the renderer (OpenGL) context or even the window 
would need to be created in a special way to support that - and if so, 
whether SDL lets you do that right now.

Cheers,
Daniel
