gtk2/gdk/wayland/gdkscreen-wayland.c
Guido Günther 8c0b11998d gdk/wayland: Take transform into account when setting physical size 
Width and height of a GdkMonitor are derived via wl_output which
talks about physical dimensions of a device and compositors usually
implement this as the untransformed values (e.g. weston, wlroots).

Since the GTK client has no way to figure out if a monitor was rotated,
transform the physical dimensions according to the applied wayland
transform to have the physical dimensions match the logical ones.

Mutter flips the physical dimensions itself but doesn't announce the
transform so this shouldn't break anything there.
