Massive changes. Too many to list here, but I'll try a summary:

* gdk/win32/*.c: Massive changes. Too many to list here, but I'll
try a summary:
1) Unify GdkPixmap and GdkImage implementation: For each
GdkPixmap, allocate a GdkImage, and vice versa.
GdkPixmapImplWin32Data has a pointer to the GdkImage.
GdkImage::windowing_data is a pointer to the GdkPixmap.
This simplifies many pixmap and image related functions a lot, and
reduces duplicated code snippets. For instance, there is only one
place in gdk/win32 where CreateDIBSection() is called, in the
function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap)
to a Windows region is almost trivial, with the bitmap bits being
readily accessible in the associated GdkImage.
All blitting between GdkPixmaps, GdkWindows and GdkImages goes
through handled the _gdk_win32_blit() function, which calls
different functions to handle the cases of blitting from pixmaps,
inside windows (scrolling), or from windows, which all require
somewhat different handling.
2) Support 256-color mode. This has long been very broken, now it
works more or less OK. Keep the logical palette for each colormap
as small as possible while allocating and freeing colors. Select
and realize the logical palette associated with a GdkColormap into
a DC before drawing or blitting.
When the display is in 256-color mode, make it possible for the
user to override the size of the palette(s) used with either the
GDK_WIN32_MAX_COLORS environment variable, or a -max-colors
command line option. It is possible to reduce the palette size all
the way down to using just the 16 static colors (which causes the
system visual to be of type GDK_VISUAL_STATIC_COLOR. This could
possibly be useful if one desperately wants to avoid color
flashing. (Note that in order for this to work properly, an as of
yet not commited fix to gdkrgb.c is needed.)
Handle the palette messages. On WM_PALETTECHANGED, call
UpdateColors() for the given window hierarchy. Do this only if a
window in some other top-level window hierarchy caused the palette
change (realized a palette). Do this max five times in a row (an
arbitrarily chosen limit), though, otherwise redraw by generating
expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole
window hierarchy by generating GDK_EXPOSE events.
3) Code cleanup in general. For instance, remove the "emulated"
X11 structs ColormapStruct, Visual and XStandardColormap. Use the
new GDK_DEBUG_* flags for debugging output in the relevant source
files. Remove the unused colormap hash table in gdkcolor-win32.c
4) Plug some resource leaks.

* gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use
g_filename_to_uri() to actually create legal URIs in the
text/uri-list data.

Implement the functions that until now just were non-functional stubs. For
2002-02-26 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkkeys-win32.c: Implement the functions that until
now just were non-functional stubs. For "hardware keycodes", we
use Windows virtual keycodes. Not scancodes, although that at
first might seem more low-level and a better match to X11
keycodes.
The Windows API is really mixed up and confused with respect to
scancodes and virtual keycodes. (Surprised?) Some scancodes are
generated by two keys on the keyboard (!), and although the
keyboard messages do have a flag to indicate which key the user
pressed, other API that take a scan code as input don't let you
specify which actual key you mean.
(update_keymap): Function to build a X11-like representation of
the keyboard. Each key has four keysyms: two levels (nonshifted
and shifted) and two groups (normal and with AltGr).
(gdk_keymap_get_direction): Use the codepage corresponding to the
thread's input locale, not the system codepage.
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkmain-win32.c
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkwindow-win32.h
* gdk/win32/gdkwindow-win32.c: Remove the input_locale and
charset_info fields from GdkWindowImplWin32. Input locale is
per-thread in Windows, and as GDK on Windows really only works
when the GDI interaction all happens in just one thread anyway,
this state can be global. Use globals _gdk_input_locale and
_gdk_input_codepage instead. Set these based on the thread's input
locale (keyboard layout, or which IME is active).
* gdk/win32/gdkevents-win32.c: Set the group and hardware_keycode
fields in GDK key events. On input locale change messages, set
the global state variables, and inform update_keymap() that it
has to rebuild the keymap.

GDK W32: Test for IME correctly
ImmIsIME() doesn't work (always returns TRUE) since Vista.
Use ITfActiveLanguageProfileNotifySink to detect TSF changes,
which are equal to IME changes for us.
Also make sure that IMMultiContext re-loads the IM when keyboard layout
changes, otherwise there's a subtle bug that could happen:
* Run GTK application with non-IME layout (US, for example)
* Focus on an editable widget (GtkEntry, for example)
* IM Context is initialized to use the simple IM
* Switch to an IME layout (such as Korean)
* Start typing
* Since IME module is not loaded yet, keypresses are handled
by a default MS IME handler
* Once IME commits a character, GDK will get a WM_KEYDOWN,
which will trigger a GdkKeyEvent, which will be handled by
an event filter in IM Context, which will finally re-evaluate
its status and load IME, and only after that GTK will get
to handle IME by itself - but by that point input would
already be broken.
To avoid this we can emit a dummy event (with Void keyval),
which will cause IM Context to load the appropriate module
immediately.
