- FDE append some code for real dri3 between linux app and this X11,
- step 1. loriePixmapFromFds get drm fd
- step 2. generate a texture by drm fd
- step 3. dixSetPrivate set texture to pixmap
- step 4. dixSetPrivate set texture to window in copy area, because of flip not support, use copy for every chanage
- step 5. update texture when damage occurs
There might still be room for improvement
