The C4819 warnings appear due to a bug on Visual C++ when running on
non-English locales, specifically CJK versions/locales of Windows.
Re-enable this, like what is done in GLib, and add a note in the
Visual C++ README.txt's to tell people about this, so that Cogl will be
built correctly.
If the DragAction has a drag handle that gets destroyed inside the
::drag-end signal handler, the destruction sequence will trigger a
callback we have in place to check if the handle is being destroyed
mid-drag, e.g. from a ::drag-motion event.
The callback on the drag handle destruction will check if we are still
in the middle of a drag and emit the ::drag-end signal to allow cleaning
up; the callback erroneously uses the drag handle as the argument for
the emit_drag_end() function — instead of the actor to which the drag
action has been attached. Also, by the time we emit the ::drag-end, we
are not dragging the actor any more, so we shouldn't be emitted the
::drag-end signal twice.
The fix is, thus, made of two parts:
- reset the in_drag boolean before emitting the ::drag-end signal
so that destroying the drag handle will not result in a double
signal emission;
- use the correct actor when calling emit_drag_end().

If the actor has a fixed position set, but it's not using the BinLayout
alignment enumeration to set its alignment, then we force the alignment
factor to 0.0; this is consistent with what happens with an explicit
alignment of CLUTTER_BIN_ALIGNMENT_FIXED.

Event handling should only apply to editable ClutterText actors, but we
also have the :selectable property to care about.
The button/touch press should position the cursor inside an editable
ClutterText; the :selectable property should be used to allow selecting
the text, either through pointer or touch dragging, via the keyboard, or
by multiple pointer clicks. If neither of these two conditions are met,
the ClutterText should just propagate the event handling further.
Allow setting a ClutterRect on the drag action and force the
dragged actor's position to be always within that rectangle (relative
to the actor's parent).

The boolean_handled accumulator will stop the signal emission if TRUE is
returned by a signal handler; the boolean_continue accumulator will stop
the signal emission if FALSE is returned. The first one is used for
event-related signals, while the latter is used for action-related
signals.
Only the signal connection. When using G_ENABLE_DIAGNOSTIC there will be
a warning for every signal connection.
We should try and discourage people from ever using the paint signal
ever again, until we can safely remove it in Clutter 2.0.
The current versions redraws all events on every redraw, which starts
getting very slow quickly. Instead simply draw only the new events
except when the cairo surface got reset, in that case redraw all events
again.

We cannot fully deprecate Geometry, because ClutterActor and ClutterText
are actually using the type in signals and properties; but we can
deprecate the API that uses this type, so that 2.0 will be able to avoid
it entirely.
The :clip property still uses ClutterGeometry, which is a very bad
rectangle type. Since we cannot change the type of the property
compatibly, we should introduce a new property using ClutterRect
instead. This also matches the ClutterActor.set_clip() API, which uses a
decomposed rectangle with floating point values, like we do with
set_position() and set_size().
Instead of only relying on the (now) deprecated BinAlignment.FIXED
enumeration value, we just ask the actor if a fixed position has been
explicitly set, under the assumption that if a developer decided to call
set_x(), set_y(), or set_position() on an actor inside a BinLayout then
she wanted the fixed position to be honoured.
This removes the last (proper) use of the BinAlignment enumeration.
The Geometry type is an *awful* representation of a integer rectangle,
as it uses unsigned integers for its size, leading to overflow issues
when unioning and intersecting. We have better rectangle types in
Cairo and Clutter, these days.
