Initial pass on API stability guarantees This introduces -DWLR_USE_UNSTABLE and adds information regarding the stability status to all headers. I started with a conservative set of headers to mark as stable: - types/wlr_matrix.h - util/edges.h - util/log.h - util/region.h - xcursor.h 2018-07-13 14:40:56 +02:00			`/*`

output: always use hardware cursors if available This changes the `wlr_output_impl.set_cursor` function to take a `wlr_texture` instead of a byte buffer. This simplifies the DRM and Wayland backends since they were creating textures from the byte buffer anyway. With this commit, performance should be improved when moving the cursor since outputs don't need to be re-rendered anymore. 2018-05-01 22:38:04 +02:00			`bool (set_cursor)(struct wlr_output output, struct wlr_texture *texture,`

backend/drm: fix frame scheduling on secondary GPUs There was a missing copy_drm_surface_mgpu call in drm_connector_schedule_frame so we asked for a pageflip with an unknown BO, resulting in ENOENT. Additionally, this commit makes schedule_frame return a bool indicating failures. This allows schedule_frame_handle_idle_timer to only set frame_pending to true if a frame has been successfully scheduled. Thus, if a pageflip fails, rendering won't be blocked forever anymore. In case a pageflip is already pending, true is returned because a frame has already been scheduled and will be sent sometime soon. 2018-10-29 20:38:57 +01:00			`bool (schedule_frame)(struct wlr_output output);`
