If a motion event handler (or other handler running from the flush-events
phase of the frame clock) recursed the main loop then flushing wouldn't
complete until after the recursed main loop returned, and various aspects
of the state would get out of sync.
To fix this, change flushing of the event queue to simply mark events as
ready to flush, and let normal event delivery handle the rest.

The MINMAXINFO struct was being populated based upon geometry hints when
GDK_HINT_MAX_SIZE flag was enabled, then promptly having its values blown
away with default values.

When events are paused, we should not return TRUE from prepare() or check().
GTK+ handles this for events that are already in the GTK+ queue, but
we also need suppress checks for events that are in the system queue - if we
return TRUE indicating that there are events in the system queue, then we'll
call dispatch(), and do nothing. The event source will spin, and will never
run the other phases of the paint clock.
(Broadway doesn't have a window system queue separate from the GDK event queue,
but we write the function the same way for consistency.)

We now have a proper MASTER/SLAVE input device split, where
the masters are virtual core input devices and we add fake hw
slave devices for the system pointer and real slave devices for
wintab devices.
We also set the proper source_device on the events so you can
tell which device sent it and properly decode the axis info.
The synaptics trackpad driver has some weird behaviour on scroll.
It pops up a window over the mouse pointer (looking like a scrollbar).
This has two problems:
* We get extra enter/leave events for the trackpad window
* We get back the trackpad window when we look for the window
under the mouse to deliver the mousewheel message.
So, we add some trackpad specific hacks to avoid this (sigh) based
on the trackpad window window class.
This fixes bug #542777 and was partially based on a patch there
from Peter Clifton.
gdk_flush() should gdk_display_sync() on all open displays.
Both for display_flush and display_sync it seems useful to call
GdiFlush, but we don't have anything extra to do for display_sync,
as there is no inherent roundtrip on win32.
This should close bug #84314
There were still cases where we didn't get a WINDOWPOSCHANGED after
a SetWindowPos() call, like e.g. with a larger minimum size than
the set size (bug #574935)
So, we revert the previous fix and now just always manually emit
a configure notify after the move_resize call. Also, we inhibit
the WINDOWPOSCHANGED configure event during the move_resize operation
to avoid multiple Configures.
There are some cases where we don't get a WINDOWPOSCHANGE such that
we generate a configure event, even if we called gdk_window_move_resize()
or similar. For instance:
* The window is fullscreen
* The window is maximized
* The specified pos/size is the same as the current one
However, as per X11 ConfigureNotify semantics we *always* want one, or
we could run into issue like e.g. bug #537296 where we're waiting for
the CONFIGURE to call gdk_window_thaw_toplevel_updates_libgtk_only().
There is no particular reason to special case this, we want to handle all
sort of normal events. The only special thing we keep is that
as an optimization we pump the message loop extra during a WINPOSCHANGED
in a modal operation as that will cause us to repaint faster.
Also, bump the arbitrary number of mainloop iterations for the timer.
I don't see why we need it at all, but at least doing more than one
iteration if needed should be nice.
When you start a window resize or move via the window menu and
don't actually change anything we're not getting an exitsizemove.
In order to work around this we also look for WM_CAPTURECHANGED.
This moves all the code from WM_SIZE, WM_MOVE, and WM_SHOWWINDOW into
one place, cleans up the code and makes sure we only send a single
configure event even if both size and position changes.
Calling PeekMessage can cause reentrant calls into the window procedure
for sent (as opposed to posted) messages, so its not safe to call
when we're not expecting reentrancy. Instead we call GetQueueStatus
when we're just looking for availible messages.

The button highlighting in testgtk works again, even with
GDK_NATIVE_WINDOWS. Unfortunately testgtk:menus still does
not work for the forced-native-window-case.
- replace GdkNativeWindow with HWND, remove type casts
- no more GdkDisplayClass::get_drag_protocol but GdkWindowImpl::get_drag_protocol
- remove *_client_message*()
There are sure regressions but basic stuff seems to be working
again after all the API breakage done with comments like
"Win32 and Quartz need to be ported still."
An event filter may add or remove filters itself. This patch does
two things to address this case. The first is to take a temporary
reference to the filter while it is being used. The second is
to wait until after the filter function is run before determining
the next node in the list to process. This guards against
changes to the next node. It also does not run functions
that have been marked as removed. Though I'm not sure if this
case can arise.

TrackMouseEvent is present in user32.dll in all Windows versions we
support. No need to look it up dynamically. No need to fallback to
_TrackMouseEvent from comctrl32.dll.
Includes fixing all callers to use the cairo region API instead. This is
usually just replacing the function names, the only difference is
gdk_region_get_rectangles() being replaced by
cairo_region_num_rectangles() and cairo_region_get_rectangle() which
required a bit more work.

WM_KILLFOCUS means that a keyboard grab (not a pointer grab), if any,
has been broken. I don't think this bug has matterd much as gtk
generates a grab-broken-event signal for both keybord and pointer
grabs being broken anyway.
