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!
