_cogl_pipeline_get_layer_with_flags accepts a CoglPipelineGetLayerFlags
flags argument and understands one COGL_PIPELINE_GET_LAYER_NO_CREATE
flag. There was a mistake with the definition of this enum though so
COGL_PIPELINE_GET_LAYER_NO_CREATE had a value of 0 and so testing for
the flag using the bitwise & operator would never find the flag set.

If a primitive is already line based then we don't need to do anything
special to draw it in wireframe mode.

If a CoglPrimitive is associated with a set of indices then we must
unref those indices when freeing the primitive to avoid a leak.

gbm_bo_get_pitch was renamed to gbm_bo_get_stride to be consistent with
how the terms pitch and stride are used throughout mesa. This updates
the Cogl backend to use the new gbm_bo_get_stride name.
For compatibility with previous version of libgbm we now explicitly
check the version of libgbm in configure.ac and expose
COGL_GBM_{MAJOR,MINOR,MICRO} defines to the code so we can conditionally
use the older gbm_bo_get_pitch() name with older versions.

The version number macros were using the @COGL_VERSION_*@
substitutions. These are always defined to 2.0.0 in the 1.x releases
so we need to use the Cogl @COGL_1_VERSION_*@ substitutions instead to
get the real version number.
When changing an implicit transition mid flight we may end up with an
easing state with a duration of zero milliseconds; this leads to the
implicit transition machinery setting the final state directly onto the
actor. If there is a running transition, though, we need to remove it
from the transitions table, otherwise it will keep running.
This regression happened when the update_transition() internal function
was merged into the create_transition() one.

Commit 802c1ac4275 fixed updating the overlay key on settings
changes, but missed the case where the setting was set to an
empty value to disable the overlay key altogether.

meta_window_group_paint tries to carefully figure out which parts of the
scene it can avoid painting. One area it avoids painting is the region of
the screen occupied by an unredirected window (if there's one present).
When subtracting from the visible region, it gets the coordinate spaces
confused, and ends up subtracting the area at the wrong offset. Fix this
by translating the rectangle subtracted from the visible region.

When the GL_EXT_unpack_subimage extension is not available and a
subregion of a texture is uploaded then it should first copy the
subregion to a newly allocated bitmap. However it was then later still
trying to prepare the upload using the original src_x and src_y values
which would cause an assertion failure. This patch fixes it to just
reset those to zero if the subregion is first copied.

PanAction is a GestureAction-subclass that implements the panning
concept for scrollable actors, with the ability to emit interpolated
signals to emulate the kinetic inertia of the panning. PanAction provides:
• pan signal, notifying users of the panning gesture status;
• pan-stopped signal, emitted at the end of the interpolated phase
of the panning gesture, if enabled;
• pan-axis property, to allow constraining the dragging to a specific
axis;
• interpolated property, to enable or disable the inertial behaviour;
• deceleration property, to customize the rate at which the momentum
of the panning will be slowed down;
• acceleration-factor property, applied to the inertial momentum when
starting the interpolated sequence.
An interactive test is also provided.

Add some accessors to simplify common tasks for GestureAction users:
• clutter_gesture_action_get_motion_delta() to get the delta
on the X and Y axis in stage coordinates since the last motion
event, and the scalar distance travelled;
• clutter_gesture_action_get_velocity() to get an estimate of the
speed of the last motion event along the X and Y axis and as a
scalar value in pixels per millisecond.

When appending (with a negative row/column parameter), the row/column
count should be incremented by 1, not 2. This also fixes layout errors
when using column/row spacing: The amount of extra space required was
calculated incorrectly due to the wrong column count.

When setting a drag handle, transform the original press
coordinates using the drag handle as reference instead of the
associated actor.
This causes the initial misplacement of drag handle in
example/drag-action when holding down the Shift key: the handle
gets placed at the main actor origin on the first drag event,
instead of following the mouse pointer.
All subsequent motion events already use the right actor when
transforming the coordinates, thus they are not affected.
