Remove redundant geometry dirtying from surface_commit() to simplify
further changes.
This code was added in commit 5df8ecac5d
"compositor: Fix partial repaints"
as the fix to:
https://bugs.freedesktop.org/show_bug.cgi?id=56538
The issue fixed by that commit was making the geometry dirty on every
attach, which caused full-surface repaints every time. The bug was
probably introduced by the opaque region changes during implementing
wl_surface.commit. The mentioned commit fixes the opaque handling by
comparing the new and old regions.
However, the commit also introduces additional checks that set
geometry.dirty. In the current code base, this should be unnecessary.
If the pending.sx or pending.sy are not zero, or if the surface size
changes, the configure() hook is responsible for applying the new
values, and so also marking the geometry dirty.
The configure() hook is only called, if there has been a new
wl_surface.attach. Nothing else can change these variables, so this
should be enough.

Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for buiding weston and its dependencies.
