mutter/src/wayland/meta-wayland-wl-shell.c
Christian Rauch aacdc0b6f1 wayland: Apply states without needing a newly attached buffer 
Applying some states, such as the minimum and maximum toplevel size, do not
require a new buffer and can operate on the old buffer. Requiring a client
to commit a new buffer just to change such states prevents setting limits
on an already existing surface buffer.
