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.
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.
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.
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.
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.

* 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.
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.
signedness of old_xpos and old_ypos to get rid of compiler
warnings.
* clutter/win32/clutter-backend-win32.c
(clutter_backend_win32_get_features): Cast the result of
glGetString to a signed char pointer to avoid compiler warnings.
* 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-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.

* clutter/win32/clutter-event-win32.c (clutter_event_check):
Removed the pointless parameter in the call to check_msg_pending.
(check_msg_pending): Fixed to use PeekMessageW instead of
PeekMessage.
