Texture->texture render possible?

[Remusforte]

SDL2 has the following commands that allow texture->texture rendering:

• SDL_RENDERER_TARGETTEXTURE (renderer flag allowing it to target textures also)
• SDL_TEXTUREACCESS_TARGET (texture flag allowing it to become a target)
• SDL_SetRenderTarget (SDL2 command to change renderer target)

I see some reference to Render Target Texture ("rtt") in render.pyx:

cdef rinfo_to_dict(SDL_RendererInfo *rinfo):

Ignore texture_formats for now.

return {
        "name" : rinfo.name,
        "software" : rinfo.flags & SDL_RENDERER_SOFTWARE != 0,
        "accelerated" : rinfo.flags & SDL_RENDERER_ACCELERATED != 0,
        "vsync" : rinfo.flags & SDL_RENDERER_PRESENTVSYNC != 0,
        "rtt" : rinfo.flags & SDL_RENDERER_TARGETTEXTURE != 0,     #<---- HERE ---
        "max_texture_width" : rinfo.max_texture_width,
        "max_texture_height" : rinfo.max_texture_height,
}

But I am not clear if it has actually been implemented in the module. Is there a way to do texture->texture renders via pygame_sdl2.render?

Thanks!
