4 Subject: [PATCH] libweston/desktop/xdg-shell: Add tiled orientation states
5
6 With the help of a newly introduced function, weston_desktop_surface_set_orientation(),
7 this patch adds missing tiled states from the xdg-shell protocol.
8 The orientation state is passed on as a bitmask enumeration flag, which the
9 shell can set, allowing multiple tiling states at once.
10
11 These new states are incorporated the same way as the others, retaining
12 the set state, but also avoiding sending new configure events if nothing
13 changed since previously acked data.
14
15 Signed-off-by: Marius Vlad <marius.vlad@collabora.com>
16 (cherry-picked from 37a3025d893def991dec59587d17672aa3bf967a)
17
18 Note that this was actually ported because libweston-desktop is not
19 embedded into libweston and the structure changed in upstream.
