This adds support for OpenGL to the GDK Windows backend using the WGL API
calls, which enables programs that uses the GTK+ GLArea widgets to work on
Windows as well.
This also adds a simple utility function to query for the version of OpenGL
that is supported by the Windows system, like the one provided by the X11
backend.
Many thanks to Alex (and Emmanuele, who started the OpenGL integration in
GTK+) who offered advice and help along the way, as well as the X11 and
Wayland backend for this work to refer to and to model upon.

Use (cairo) input shape of the window to check whether a point is inside or not
inside the window.
If it is, let the default window procedure do its thing (which seems to be
working all right in all known cases).
If it isn't, override the default window procedure and tell WM what we think.
Don't do any of the above if the window has CSD-incompatible styles (WS_BORDER
or WS_THICKFRAME).
This is a crude kind of substitute for window input shape support (which W32
does not seem to have). Still probably enough to be positive about input shapes
support.

Due to the work on gdk_cursor_new_from_surface (commit b2113b73),
get_cursor_for_pixbuf() in GdkDisplayClass was converted to
get_cursor_for_surface(), which means the GDK Win32 backend needs to be
updated for the code to build and run on Windows, plus some function
prototypes and declarations/calls need to be updated as well.

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
- 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."
In particular, the following functions are gone:
- gdk_screen_get_default_colormap()
- gdk_screen_set_default_colormap()
- gdk_screen_get_system_colormap()
- gdk_screen_get_rgba_colormap()

Bug 566628 - gdk_display_close always asserts on win32
* gdk/win32/gdkdisplay-win32.c
(_gdk_windowing_set_default_display): Allow also a NULL parameter
in the g_assert(). Still don't actually do anything in this
function, though.

* gdk/win32/gdkdisplay-win32.c: Don't bother looking up
EnumDisplayMonitors and GetMonitorInfoA dynamically, they are
present in NT-based Windows since Windows 2000.
(enum_monitor): For some reason the MONITORINFOEX struct in
mingw-win64 is different than the proper one as in MSDN and 32-bit
mingw, so just copy the proper definition here.

* gtk/gtkprintoperation.c : check surface status after ceating a pdf.
Avoids crashing when the target can not be written, bug #537685
* gdk/win32/gdkdisplay-win32.c : runtime linking of ProcessIdToSessionId
* gtk/gtkfilesystem.c : variadic macros are not supported with c89 and
it was not needed here anyway.

2008-06-11 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkdisplay-win32.c (gdk_display_get_name): As we don't
support Win9x anyway, we can use ProcessIdToSessionId()
unconditionally.

2005-10-14 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkdisplay-win32.c: Remove the clipboard viewer code.
It didn't really do anything useful, and was just confusing and
incomplete. Comments claimed we don't do delayed rendering, but in
fact we do, for images. (The delayed rendering code has other
problems, though, see #168173.) The clipboard viewer code was
probably even buggy (the WM_CHANGECBCHAIN handled didn't propagate
the message when necessary). It was just test code, it said so in
a comment. Add something similar back later if necessary.
(_win32_on_clipboard_change,
_gdk_win32_register_clipboard_notification): Remove.
(gdk_display_supports_selection_notification,
gdk_display_request_selection_notification): Always just return
FALSE. We didn't generate any GDK_OWNER_CHANGE events anywhere.
2005-09-09 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkdisplay-win32.c (gdk_display_get_name): Cache the
display name. There is only one GdkDisplay on Win32, and
constructing the display name isn't entirely trivial, so cacheing
is probably worth it. For instance GIMP calls this function a lot.
(gdk_display_open): Call gdk_display_get_name() to prime the
cached name.
(gdk_display_get_n_screens, gdk_display_get_screen,
gdk_display_get_default_screen): Verify parameter correctness like
the X11 backend does.
* gdk/win32/gdkscreen-win32.c (gdk_screen_make_display_name):
Return a freshly allocated string, as the API specifies. Fixes a
heap corruption problem that caused random errors and crashes in
GIMP, for instance.
2005-04-04 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkmain.c (_gdk_win32_cf_to_string): New debugging
function, to log a clipboard format name symbolically.
(_gdk_win32_data_to_string): Also new, to log random data bytes.
Implement delayed rendering on Win32, specifically for transfering
images through the clipboard from GTK+ apps to other
apps (#168173, implementation by Ivan Wong):
* gdk/win32/gdkevents-win32.c (gdk_event_translate):
Handle WM_RENDERFORMAT.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c: Add _format_atom_table,
_delayed_rendering_data and _image_bmp.
* gdk/win32/gdkmain-win32.c: Initialize _image_bmp.
* gdk/win32/gdkproperty-win32.c (gdk_property_change):
Accept formats other than GDK_TARGET_STRING or _utf8_string, and
assume they are handled through delayed rendering.
* gdk/win32/gdkselection-win32.c (gdk_selection_convert):
Return all available formats (including those registered by GTK+
apps) on request_targets.
(gdk_selection_property_get): We should append a zero byte like
X11 does.
(gdk_win32_selection_add_targets): New function, for
gtkselection's use. Win32 requires that the clipboard owner
registers all valid formats even if the owner wants delayed
rendering.
(_gdk_win32_selection_convert_to_dib): New function. Convert
images to DIB using gdk-pixbuf.
* gdk/win32/gdkwin32.h: Declare gdk_win32_selection_add_targets().
* gtk/gtkselection.c (gtk_selection_add_target,
gtk_selection_add_targets): Call gdk_win32_selection_add_targets()
to register target formats.
* gdk/gdk.symbols: Add gdk_win32_selection_add_targets().

[merged from gtk-2-6 branch]
* gdk/win32/gdkdrawable-win32.c : let dash_offset shift the start of
the line pattern not the start of the line. Fixes bug #171641.
* gtk/makefile.msc.in : follow .symbols changes
* gdk/win32/gdkwindow-win32.c : declare and resolve GetAncestor()
dynamically. (It is not available in _WIN_VER <= 0x0400)
* gdk/win32/makefile.msc : removed gdkpango-win32.obj
* gtk/gtkhsv.c gtk/gtkstyle.c : use G_PI instead of M_PI
[also applied to gtk-2-6 branch]
* gdk/makefile.msc gdk-pixbuf/makefile.msc : handle gdk*alias.def
* gdk/makefile.msc.in : add gtkmnemonichash.obj
* test/testgtk.c(set_parent_signal) : use g_message instead of
g_print to keep the 'testgtk --bench=all' output clean
2005-03-20 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkdisplay-win32.c (gdk_display_get_name): Return the
Terminal Services session number, window station name (always
"WinSta0" in interactive processes), and desktop name (typically
"Default"), concatenated with backslash separators.
(gdk_display_open): Accept only NULL or the string
gdk_display_get_name() returns as display name.
2005-03-16 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkdisplay-win32.c (_win32_on_clipboard_change): Print
debugging output only if asked for, not always.
* gdk/win32/*.c: Use the %+d%+d format for coordinate pairs in
debugging printout instead of +%d+%d. Misc other additions and
cosmetic improvements to debugging printouts. Use API_CALL() and
GDI_CALL() macros in more places.
* gdk/win32/gdkwindow-win32.c (gdk_window_move, gdk_window_resize,
gdk_window_move_resize): To detect child windows, check whether
the real parent is not the desktop window, instead of relying on
the GDK window type being GDK_WINDOW_CHILD. Foreign GtkPlug
windows have a GDK window type GDK_WINDOW_FOREIGN, but are still
de facto child windows.
2004-09-03 Tor Lillqvist <tml@iki.fi>
* gtk-zip.sh.in: List the three theme gtkrc files separately, zip
doesn't do anything if one of the files on its command line
doesn't exist.
Handle changes of screen resolution on Win32. (#151581, reported by
Arjohn Kampman)
* gdk/win32/gdkwindow-win32.c (_gdk_windowing_window_init,
_gdk_root_window_size_init): Factor out setting the root window's
size (as the size of the union of all monitors) to a new function.
* gdk/win32/gdkdisplay-win32.c (gdk_display_open,
_gdk_monitor_init): Factor out the monitor query to a new
function.
* gdk/win32/gdkprivate-win32.h: Declare above new functions.
* gdk/win32/gdkevents-win32.c (gdk_event_translate,
handle_display_change): Handle WM_DISPLAYCHANGE by calling the
above two functions, and emitting the "size_changed" signal on our
(only) GdkScreen.
2004-08-22 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkdisplay-win32.c (enum_monitor, gdk_display_open):
Report whole of (primary) monitor, including any taskbars.
Excluding the taskbar area from the "root window" reported to GDK
doesn't seem to be that useful although gdk/win32 had been doing it
for a very long time. (#149013, see also #145467 and #148526)
2004-08-06 Hans Breuer <hans@breuer.org>
* gdk/win32/gdkwindow-win32.c : make it compile and more
similar to the X11 implementation [backward compatibility
for GDK_WINDOW_TEMP, GDK_INPUT_ONLY (fixes bug #148702),
use the *screen* function variants, dont reparent already
destroyed]
(get_visible_region) : take the win32 part into account
(_gdk_windowing_window_destroy) : remove from handle table
* gdk/win32/gdkdisplay-win32.c : added
gdk_display_(request|supports)_selection_notification ()
with a currently mostly pointless implementation ;-)
* gtk/gtkfilesystemwin32.c (*_to_path) : same changes as on *NIX,
plugs memory leak
(gtk_file_system_win32_render_icon) : use new GTK_STOCK_DIRECTORY
* gtk/makefile.msc.in demos/gtk-demo/makefile.msc.in
gtk/stock-icons/makefile.msc tests/makefile.msc : updated
* gdk/gdk.def gtk/gtk.def : updated externals
* tests/testiconview.c : remove unneeded dirent.h inclusion
