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.
The Win32 backend now implements the create_context method which
creates a context and binds it to a 1x1 invisible window. That way
there will always be a context bound and the features can be retrieved
without creating the default stage. This reflects the changes in
1c6ffc8..b245d55 to the GLX backend.
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.
* 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.

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.
