    app: don't upscale preallocated display buffers by GIMP_DISPLAY_RENDER_MAX_SCALE
    
    After commit 8029508fbef8b2b5b3abd3be8a3fbb7d46654f86, we always
    render the image in chunks that are at most
    GIMP_DISPLAY_RENDER_BUF_WIDTH x GIMP_DISPLAY_RENDER_BUF_HEIGHT,
    even when the window's scale factor is > 1.
