    Only scanout when the texture matches the display size · 58debd72

    Otherwise drmModeAtomicCommit() in DrmOutput::doAtomicCommit() fails due
    to unmatched buffer sizes.
    
    While rendering continues working properly, this makes drm freak out and
    try to go back to a previous state (see the test commit in
    presentAtomically()) that in turn starts issuing screen events to every
    process even though it's just to say the same thing. The fact that this
    happens per frame makes the system unusable as soon as fullscreen starts
    happening on a scaled display.
    
    Another thing we could do is get EglGbmBackend::scanout() to take care
    of the resizing.
