This has two advantages:
1) In many backends, this is faster as we can terminate the window
hierarchy traversal earlier
2) When used in gdkdisplay.c::get_current_toplevel() to get the
current toplevel that has the pointer we now correctly return
a toplevel with the pointer in it where the pointer is inside
some foreign subwindow of a toplevel window.
The second advantage fixes some bugs in client side event generation
when the pointer is inside such a foreign child window.
Set the input_window_destroy and input_window_crossing methods of the
GdkWindowImplIface on Windows. Add implementation of
_gdk_input_crossing_event that is mostly dummy, though.
The X11 queue_translation operation uses NextRequest to get the serial
of the XCopyArea operation where the translation should end. However,
if the gc passed to gdk_draw_drawable has a non-flushed clip region
(which it commonly has now for the window clipping) then the next
operation will be the GC flush, not the XCopyArea.
To handle this right we now pass in the GC to be used to
queue_translation and ensure that it is flushed before calling
NextRequest().
Implement _gdk_win32_window_destroy() by just renaming
_gdk_windowing_window_destroy(), removed superfuous stub.
Also cleaned up implementations of gdk_win32_window_set_background()
and gdk_win32_window_set_back_pixmap() - removed stuff now done at the
respective gdk_window_*() function.
Resurrcetion and adaption of find_window_for_mouse_event(). The window
receiving the WM_MOUSEMOVE, WM_?BUTTONDOWN is not necessarily the one
interested in GDK_(ENTER|MOTION|LEAVE)_NOTIFY
http://bugzilla.gnome.org/show_bug.cgi?id=588373
Also added some more more TODO_CSW and disabled print_event(): it can not
cope with the new _gdk_windowing_got_event() eating/morphing events.
Turns out pygtk build broke due to the argument addition to draw_drawable.
So, we now add a new vfunc for the new draw_drawable and are thus
backwards compat.

Bug 559408 - Transparency lost when images are copied between GTK+
and the clipboard on Windows
The code in gdkselection-win32.c is simplified quite a lot. When
an image is stored on the clipboard from GTK+, only the "PNG" and
CF_DIB formats are advertised. PNG is our preferred format because
it can losslessly represent any image that gdk-pixbuf can handle,
even with alpha, unambiguously. CF_DIB is also advertised because
of its ubiquitous support in Windows software.
Delayed rendering is used as before, so for other data than text
nothing is actually stored on the clipboard until some app asks
for it.
It's pointless to advertise images formats like "image/png" or
"image/x-MS-bmp" that no other Windows application is going to
look for anyway. Likewise it's pointless to store text under
formats like "text/plain" or "UTF8_STRING". Just store
CF_UNICODETEXT. CF_TEXT will be available as a synthesized format
anyways.
Office 2007 offers and asks for images in PNG format using the
registered clipboard format name "PNG", so we do likewise. If the
"PNG" format is available that is preferred when copying to GTK+
from the clipboard.
Unfortunately Word 2007 still uses CF_DIB without handling
alpha. But PowerPoint 2007 uses PNG if available and handles alpha
correctly. Both Word and Powerpoint offer PNG with alpha nicely.
Firefox and IE7 offer images that contain alpha as 32-bit version
3 BI_RGB DIBs with the undocumented "extra" bytes actually being
alpha. Also, alpha is premultiplied into the RGB bytes, presumably
because that is how AlphaBlend() wants such DIBs. That is also
taken care of. At least for Firefox it easy to be sure that a
CF_DIB on the clipboard is from Firefox.
Also some general stylistic cleanup, comment improvements, and
improvements of debugging printout especially in the clipboard
handling. Those are not detailled below.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkgmain-win32.c: Move some globals that were used
only in gdkselection-win32.c to be local to that file.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): Don't
bother checking if text to be placed on the clipboard consists of
only ASCII.
* gdk/win32/gdkselection-win32.c: Add static variables for a list
of GdkPixbuf-supported formats, well-known registered clipboard
formats for images, and for GdkAtoms for well-known image and text
formats.
(_gdk_win32_selection_init): Initialize above static variables.
(selection_property_store) (gdk_selection_property_get)
(_gdk_selection_property_delete): Don't use a FIFO of GdkSelProps
for a window after all, it breaks testtext. See bug #163844.
(gdk_selection_convert): When converting to the TARGETS format,
i.e. when the caller wants to know what clipboard formats are
available, if PNG is available we report just that and skip
CF_DIB, JPEG and GIF even if advertised.
If CF_UNICODETEXT is available, report only UTF8_STRING.
When converting to the UTF8_STRING format, i.e. when the caller
wants text from the clipboard, try just CF_UNICODETEXT. There is
no point in trying CF_TEXT as Windows will synthesize
CF_UNICODETEXT from CF_TEXT anyway, if some app has stored just
CF_TEXT.
When converting to the image/bmp format, i.e. when the caller
wants an CF_DIB image from the clipboard, we check if the DIB is a
version 3 32-bit BI_RGB one that is likely to actually contain
alpha in the "extra" bytes. Such a DIB is likely to have
premultiplied alpha even, at least in the case of Firefox 3 and
IE7. We then edit the DIB in-place into a version 5 one in
BI_BITFIELDS format and undo the alpha premultiplication.
In any case, prepend a BMP file header before letting go of the
data which will be fed to the gdk-pixbuf bmp loader by upper
levels.
(gdk_win32_selection_add_targets): If some kind of pixmap image
format is being added, actually advertise just PNG and
CF_DIB. Note that alpha won't be stored on the clipboard through
CF_DIB. This is because gdk-pixbuf's bmp loader doesn't save
alpha. Furthermore, few if any non-GTK+ Windows apps seem to
understand a version 5 DIB with proper alpha anyway.
(_gdk_win32_selection_convert_to_dib): Simplified muchly.
