[Florian MÃllner <fmuellner src gnome org>]

commit 23a4d4c69e071030197f2aaea913d4cd742c48c9

    texture-cache: Don't share requests for uncachable textures
    
    Make create_texture_and_ensure_request() aware of the caching
    policy to avoid returning the same texture for different
    images.
