This can happen for instance if the client that started the drag
crashes. Weston would crash because of the invalid surface pointed by
device->drag_surface.
Fix this by reseting the drag surface to nil on a destroy listener.
The surface data structure is now a list of list of surfaces. The core
compositor defines the fade and cursor layer, and it's up to the shell to
provide more layers for the various surface types it implements.
We can now clip the surface bounding box against the previous frame
opaque clip, and then just union the result (visible damage) into
compositor->damage immediately.
DPMS kicks in only when wscreensaver is launched, in the moment that shell
call lock() for the second time. Backlight control internals are managed by
libbacklight:

This allows each output back end to optimize drawing using overlay planes
and cursors (yet to be integrated). If a surface is assigned to a
plane, the back end should clear its damage field so that the later
repaint code won't look at it.
Ideally, we would want to use <modifier>+Scroll binding but that will have
to wait for axis events. For now we just use keybindings. Zoom in/out with
Super+Up/Down.
We just set the input region to the bounding box of the window frame
and set the opaque region to be the opaque rectangle inside the window
if the child widget is opaque.
We never want to update the transform and then damage below. Damage
below is always used to trigger a repaint where the surface used to be
so we need to record the damage before updating the transform.
Needed for implementing drag'n'drop icons. When a drag starts, the
compositor will position the top-left corner of the client supplied
icon surface at the cursor hotspot. On the first attach to that
surface, the client may want to reposition it but shell->map did not
take sx and sy parameters.
This changes shell->map interface to take sx and sy parameters and
change dekstop shell implementation to update the position of a
surface of type none according to those parameters. Since a surface
of type none won't actually be mapped, the effect of this change is
only visible for surfaces that are made visible by the compositor.

Surfaces like drag'n'drop icons shouldn't receive events as a normal
surface but are still created by the client so add a way for the
compositor to enable or disable the picking of a client surface.

The condition to return from surface_attach with a null buffer involves
es->output being non-null. However if a surface was just created this
field would be null and an attach of a null buffer would cause the
compositor to crash.
The other crash happened if surface_attach was called twice with a
null buffer after a valid buffer was attached to the surface. Since
es->buffer was not being set to NULL, surface_attach() would call
wl_list_remove(&es->buffer_destroy_listener.link) twice for the same
surface.

I know it's hard to figure out what the shells or backends will be
using as internal API at this point but we can try to minimize the
amount of WL_EXPORT being used anyway.

As weston_surface_update_transform() automatically applies before and
after damage on surface geometry change, we don't need to explicitly add
the same damage in motion_notify() for the cursor surface.
We still need the side-effect, that is scheduling a repaint.

Round off fractions from non-transformed surface position coordinates.
Transformed surface moved by a client may have non-integer position
coordinates. That is required to prevent drifting on continuous
resizing.
We can round the position to integers when the surface is not (anymore)
transformed.
This change may fix a rounding inconsistency in the opaque region setup,
where the rectangle is initialised from the coordinates without explicit
rounding operation.

Move the call to assign an output from weston_surface_configure() to
weston_surface_update_transform().
As update_transform takes new geometry into use, it should also reassign
the output for the surface, but only if an output was already assigned.
Add explicit assing output calls to where we relied on
weston_surface_configure() unconditionally assigning the output.

Move the surface opaque region setup from weston_surface_configure() to
weston_surface_update_transform(), so we have less reason to call
update_transform from configure. Opaque region depends on geometry,
after all.
Also move the opaque field from weston_surface to
weston_surface::transform to make this obvious.

Remove redundant weston_surface_update_transform() calls from within
output repaint paths, and add a comment that we need to rely on
surface->geometry.dirty == 0 within the repaint sub-functions.
Now that weston_surface_update_transform() does damage as needed, and
weston_output_repaint() explicitly calls update_transform, we can reduce
the updates in rotate_grab_motion() to simply scheduling a repaint. This
will guarantee that the change in rotation ends up on screen ASAP.

weston_surface_update_transform() is similar to
weston_surface_configure() in that it changes the surface region on
screen. Unlike configure, update_transform forgets to deal damage at
all, yet it is the only place where we can do damage_below() as needed.
Add a damage_below call to deal damage for the old surface region only
when needed. This uses the cached state from surface->transform to get
the old region.
Add a damage call to deal damage for the new surface region, after
updating the cached state.
Add a repaint call, since we have changed the scene and should render it
out.
This change fixes the rotation not updating the screen properly.

The non-transformed case looked a little odd, calling
weston_surface_to_global(), since it already tests for transform.enabled
and simply uses width, height for the box.
Streamline it, by open-coding weston_surface_to_global(), and avoiding
another call into weston_surface_update_transform(). This way it does
not look suspicious to me.

In surface_compute_bbox(), call surface_to_global_float() instead of
weston_surface_to_global(). This avoids the recursion:
weston_surface_update_transform()
weston_surface_update_transform_enable()
surface_compute_bbox()
weston_surface_to_global()
weston_surface_update_transform()
which might be non-obvious when reading the code.
Computing the min and max coordinates in floats, we can have a tight
rounding margin by using floor() and ceil().

Split two helper functions out of weston_surface_update_transform() to:
- make the code clearer
- update the bounding box properly even if transformation fails
- unify the return point
Also add a comment on what matrix.d[12] is.
