527ad961ab clutter-event-win32: Emit multiple events for WM_MOUSEWHEEL Messages
It's possible that a single WM_MOUSEWHEEL event can arrive with a
scroll amount greater than WHEEL_DELTA. Previously it would accumulate
these amounts but it would still only emit a single event per
message. For example, if a message arrived that is worth two
WHEEL_DELTAs then it would emit one event and leave scroll_pos as
+WHEEL_DELTA. If the wheel is then scrolled in the opposite direction
then wheel delta would end up as zero and the scroll event would get
lost.

This patch fixes it so that it always emits enough events to put
scroll_pos back to less than WHEEL_DELTA.

2c8d73f047 clutter-event-win32: Directly enqueue events in message_translate
Previously the window procedure for the stage window would always
create a ClutterEvent struct for every message and then pass that on
to message_translate to fill in the details. message_translate could
return FALSE to abandon the event. Instead of this, message_translate
now creates and queues the event itself whenever it sees a message
that could translate to an event. The function now returns void. This
has a number of advantages:

* It saves redundantly allocating events for messages that Clutter
  doesn't care about.

* A single message can now easily be translated into multiple events.

* There were some messages that were handled and did not fill in the
  event struct but did not cause the function to return FALSE. I think
  this would end up with a CLUTTER_NOTHING event being emitted.

79acb088e7 Remove mentions of the FSF address
Since using addresses that might change is something that finally
the FSF acknowledge as a plausible scenario (after changing address
twice), the license blurb in the source files should use the URI
for getting the license in case the library did not come with it.

Not that URIs cannot possibly change, but at least it's easier to
set up a redirection at the same place.

As a side note: this commit closes the oldes bug in Clutter's bug
report tool.

a2afc9d7ba win32: Fixup compilation errors from b398292089
That commit added some Win32 code which breaks compilation.

Thanks to Samuel Degrande for help with this.

b398292089 device: Impose per-backend DeviceManager
The DeviceManager class should be abstract in Clutter, and implemented
by each backend, as different backends will have different ways to
detect, initialize and list devices; the X11 backend alone has *two*
ways of dealing with devices.

This commit makes DeviceManager an abstract class and delegates the
device initialization and enumeration to per-backend sub-classes.

The responsible for creating the device manager is, obviously, the
backend singleton.

The X11 and Win32 backends have been updated to the new layout; the
Win32 backend has been updated blindly, so it might require additional
testing.

74dbcede25 win32: Experimental implementation of device support
Mostly lifted from the core pointer and keyboard X11 backend support.

The win32 backend registers two devices (a core pointer and a core
keyboard) and assigns them to the event structure when doing the
translation from native events to Clutter events.

Thanks to: Samuel Degrande <Samuel.Degrande@lifl.fr> for testing this
patch.

14a28620ae win32: Use an invisible cursor when cursor-visible is FALSE
The win32 backend now handles the WM_SETCURSOR message and sets a
fully transparent cursor if the cursor-visible property has been
cleared on the stage. The icon is stored in the library via a resource
file. The instance handle for the DLL is needed to load the resource
so there is now a DllMain function to grab the handle.

c6fba47a52 Hide clutter_context_get_default()
The clutter_context_get_default() function is private, but shared
across Clutter. For this reason, it should be prefixed by '_' so
that the symbol is hidden from the shared object.

1fcddb3b10 [win32] Track mouse leave messages
Bug 1178 - No enter / leave events on actors when pointer leaves the
           stage window

This patch causes the Win32 backend to emit CLUTTER_LEAVE events when
a WM_MOUSELEAVE event is received in the same way that f505536 does
for the X11 backend.

Windows will only send WM_MOUSELEAVE events if they are previously
requested using TrackMouseEvent so this needs to be called whenever
the mouse enters the window. There is no WM_MOUSELEAVE event but we
can detect when the mouse enters because we get a WM_MOUSEMOVE event.

3fb00f9cdd Bug 1100 - WM_SIZE not handled correctly, user_resize and
window_style correction.

	* clutter/win32/clutter-stage-win32.c (get_window_style): Remove
	the WS_MAXIMIZEBOX style if the stage isn't resizable.
	(clutter_stage_win32_set_user_resize): Queue a redraw of the
	window frame when the user_resize property is changed.

	* clutter/win32/clutter-event-win32.c (message_translate): Don't
	update the size of the stage when handling WM_SIZE messages that
	result from the stage being minimized. Thanks to Roman Yazmin.

* clutter/win32/clutter-event-win32.c (message_translate): The
	coordinates in a WM_MOUSEWEEL message are given relative to the
	screen so they need to be converted to client coordinates before
	use. Thanks to Roman Yazmin.

e4304e2d0a * clutter/win32/clutter-stage-win32.c: Updated to the new layout
API. All code to do with positioning the stage has been removed so
	the window is left where Windows wants to put it and it can not be
	moved with clutter_actor_set_position.

	* clutter/win32/clutter-stage-win32.h (ClutterStageWin32): Remove
	win_xpos and win_ypos.

	* clutter/win32/clutter-event-win32.c (message_translate): Remove
	the handler for WM_MOVE because the stage no longer cares where it
	is positioned.

3d1f2a0859 Added support for foreign windows to the Win32 backend.
* clutter/win32/clutter-stage-win32.c
	(clutter_stage_win32_request_coords): Don't resize foreign
	windows.
	(clutter_stage_win32_unrealize): Don't destroy foreign windows.
	(clutter_stage_win32_init): Added initialiser for is_foreign_win.
	(clutter_win32_get_stage_from_window): Resort to looking in the
	stage list if the window isn't the right window class so that it
	can still find stages with foreign windows.
	(clutter_win32_set_stage_foreign): New public function to set a
	foreign window for a stage.

	* clutter/win32/clutter-event-win32.c
	(clutter_win32_disable_event_retrieval): New public function to
	disable event retrieval.
	(message_translate): Don't handle WM_SIZE or WM_MOVE for foreign
	windows.

	* clutter/win32/clutter-backend-win32.h (struct
	_ClutterBackendWin32): Added a flag to disable event retrieval

	* clutter/win32/clutter-backend-win32.c
	(clutter_backend_win32_ensure_context): Update debug note to
	include whether the stage is foreign or not.

0b8a500fca Upgraded the Win32 backend to work with the multi-stage
subclassing code.

	* clutter/win32/clutter-stage-win32.h: 
	* clutter/win32/clutter-stage-win32.c: Now inherits from
	ClutterGroup and implements ClutterStageWindow instead of
	inheriting directly from ClutterStage.

	* clutter/win32/clutter-event-win32.c (message_translate): Now
	takes an extra parameter to return whether DefWindowProc should be
	called. This is needed to prevent the default WM_CLOSE handler
	from destroying the window.

	* clutter/win32/clutter-backend-win32.c
	(clutter_backend_win32_dispose): Destroy all of the stages using
	g_slist_foreach as per bug #871. Now also destroys the GL context.
	(clutter_backend_win32_get_features): Added assertions to ensure
	there is a valid GL context.
	(clutter_backend_win32_ensure_context): Accepts NULL stage. Gets
	implementation pointer from the stage.

	Upgraded for multi-stage support.

	* clutter/win32/clutter-stage-win32.c
	(clutter_stage_win32_request_coords): Fixed so that it doesn't set
	the position or size if it hasn't changed. This was causing
	problems when the window was resized using the top left corner. In
	that case the window receives resize and move messages separately
	which caused the window to flash at a different size or position
	while one message was handled before the other.
	(clutter_stage_win32_realize): Added PFD_GENERIC_ACCELERATED to
	the list of pixel format flags to force it to use hardware
	acceleration.
