0.9.0

wlroots 0.9.0 includes the following breaking changes:

layer_shell: set layer of existing surface #1842

The layer of a layer surface may now be changed at runtime. The layer field has been removed from struct wlr_layer_surface_v1 and introduced to struct wlr_layer_surface_v1_state.

backend/drm: add support for custom modes #1881

wlr_drm_connector_add_mode now returns the new mode instead of a bool.

Simplify globals implementation by removing destructors #1915

Destructors and resource lists for static globals have been removed.

Improve presentation-time API #1919

Instead of calling wlr_presentation_surface_sampled at render time and wlr_presentation_send_surface_presented at presentation time, most compositors now just need to call wlr_presentation_surface_sampled_on_output at render time. Compositors that call wlr_buffer_ref need to call wlr_presentation_surface_sampled when they ref the buffer, wlr_presentation_feedback_send_presented when this buffer has been presented for the first time and then wlr_presentation_feedback_destroy.

output: re-introduce atomic mode, enabled, scale and transform #1797

• Compositors now need to call wlr_output_commit after wlr_output_enable, wlr_output_set_mode, wlr_output_set_custom_mode, wlr_output_set_transform or wlr_output_set_scale
• wlr_output_set_mode no longer implicitly enables the output, compositors need to call wlr_output_enable as well
• Compositors now need to call wlr_output_rollback after wlr_output_attach_render if they decide not to render
