Most of the pending output state is not forwarded to the backend prior to an output commit. For instance, wlr_output_set_mode just stashes the mode without calling any wlr_output_impl function. wlr_output_impl.commit is responsible for applying the pending mode. However, there are exceptions to this rule. The first one is wlr_output_attach_render. It won't go away before renderer v6 is complete, because it needs to set the current EGL surface. The second one is wlr_output_attach_buffer. wlr_output_impl.attach_buffer is removed in [1]. When wlr_output_rollback is called, all pending state is supposed to be cleared. This works for all the state except the two exceptions mentionned above. To fix this, introduce wlr_output_impl.rollback. Right now, the backend resets the current EGL surface. This prevents GL commands from affecting the output after wlr_output_rollback. This patch is required for FBO-based outputs to work properly. The compositor might be using FBOs for its own purposes [2], having leftover FBO state can have bad consequences.
