Add swayc_change_layout function, which changes either layout or
workspace_layout, depending on the container type. Workspace being
always L_HORIZ makes this much more i3-compatible.
Replace `update_view_border()` with `update_container_border()`. The latter
should handle both the case where the container is a view or if the container
has children.
The previous implementation of focus handling assumed that only views can be
focused. Containers can also be focused with a command like `focus parent` or
`focus child`.
Change `set_focused_container()` to handle the case of the given container
being a container with children and update borders accordingly.
When titlebar is hidden, top border of the topmost view inside
tabbed/stacked container will not be drawn. This is changed in layout.c
On the other hand, top border should be drawn sometimes, for example
when titlebar is hidden on a view that is not the topmost inside
tabbed/stacked container. This is changed in border.c
Panels were explicitly rendered by calling wlc_surface_render in
handle_output_pre_render. Calling wlc_surface_render does not set the
surface's geometry (like wlc_view_set_geometry does). Sway did not call
wlc_view_set_geometry for panels, so wlc defaulted their geometry to be at
the origin. This is not correct for bars unless their location is top.
Furthermore, for a surface to receive pointer events, its mask has to be
set to visible. This causes wlc to render these surfaces, causing panels
and backgrounds to be rendered twice.
This commit makes panels and surfaces visible, sets the correct geometries
and removes the code that explicitly rendered them.
Tabbed/stacked containers are now created only if a view is present on
the workspace. If a view is created on previously empty tabbed/stacked
workspace, it gets wrapped in a container.
Prior to this commit all windows (e.g. shell surfaces) were handled the same
way in handle_view_created. Since backgrounds and panels have to be treated
differently, they could not be shell surfaces. This changes checks whether
a client is a background or a panel in handle_view_created and exists to
let them be dealt with elsewhere.
