* remotes/kraxel/tags/egl-20211105-pull-request:
  ui/gtk-egl: blitting partial guest fb to the proper scanout surface
  ui/gtk: gd_draw_event returns FALSE when no cairo surface is bound
  ui/gtk-egl: guest fb texture needs to be regenerated when reinitializing egl
  ui/gtk-egl: make sure the right context is set as the current
  ui/gtk-egl: un-tab and re-tab should destroy egl surface and context
  virtio-gpu: splitting one extended mode guest fb into n-scanouts
