2000-05-02  Tor Lillqvist  <tml@iki.fi>

Large changes to the Win32 backend, partially made necessary by
the changes to the backend-independent internal
structures. Attempts to implement similar backing store stuff as
on X11. The current (CVS) version of the Win32 backend is *not* as
stable as it was before the no-flicker branch was merged. A
zipfile with that version is available from
http://www.gimp.org/win32/. That should be use by "production"
code until this CVS version is usable. (But note, the Win32
backend has never been claimed to be "production quality".)

* README.win32: Add the above comment about versions.

* gdk/gdkwindow.c: Don't use backing store for now on Win32.

* gdk/gdk.def: Update.

* gdk/gdkfont.h: Declare temporary Win32-only functions. Will
presumably be replaced by some more better mechanism as 1.4 gets
closer to release shape.

* gdk/makefile.{cygwin,msc}: Update.

* gdk/win32/*.c: Correct inclusions of the backend-specific and
internal headers. Change code according to changes in these. Use
gdk_drawable_*, not gdk_window_* where necessary.

* gdk/win32/gdkdnd-win32.c: Use MISC selector for GDK_NOTE, not
our old DND.

* gdk/win32/gdkdrawable-win32.c (gdk_win32_draw_text): Don't try
to interpret single characters as UTF-8. Thanks to Hans Breuer.
Use correct function name in warning messages.

* gdk/win32/gdkevents-win32.c: Use correct parameter lists for the
GSourceFuncs gdk_event_prepare and gdk_event_check.
(gdk_event_get_graphics_expose): Do implement, use
PeekMessage. Thanks to Hans Breuer.
(event_mask_string): Debugging function to print an GdkEventMask.
(gdk_pointer_grab): Use it.

* gdk/win32/gdkfont-win32.c: The Unicode subrange that the
(old) book I used claimed was Hangul actually is CJK Unified
Ideographs Extension A. Also, Hangul Syllables were missing.
Improve logging.

* gdk/win32/gdkgc-win32.c: Largish changes.

* gdk/win32/gdkim-win32.c (gdk_set_locale): Use
g_win32_getlocale() from GLib, and not setlocale() to get current
locale name.

* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkwin32.h: Move stuff from gdkprivate-win32.h to
gdkwin32.h, similarily as in the X11 backend.

* gdk/win32/gdkwindow-win32.c (gdk_propagate_shapes): Bugfix,
assignment was used instead of equals in if test. Thanks to Hans
Breuer.

* gdk/win32/makefile.{cygwin,msc}
* gtk/makefile.{cygwin,msc}: Updates. Better kludge to get the
path to the Win32 headers that works also with the mingw compiler.

* gtk/gtkstyle.c: Include <string.h>.

/*************************************************************
* gtk_style_attach:
* Attach a style to a window; this process allocates the
* colors and creates the GC's for the style - it specializes
* it to a particular visual and colormap. The process
* may involve the creation of a new style if the style
* has already been attached to a window with a different
* style and colormap.
* arguments:
* style:
* window:
* results:
* Either the style parameter, or a newly created style.
* If the style is newly created, the style parameter
* will be dereferenced, and the new style will have
* a reference count belonging to the caller.
*
* FIXME: The sequence -
* create a style => s1
* attach s1 to v1, c1 => s1
* attach s1 to v2, c2 => s2
* detach s1 from v1, c1
* attach s1 to v2, c2 => s3
* results in two separate, unlinked styles s2 and s3 which
* are identical and could be shared. To fix this, we would
* want to never remove a style from the list of linked
* styles as long as as it has a reference count. However, the
* disadvantage of doing it this way means that we would need two
* passes through the linked list when attaching (one to check for
* matching styles, one to look for empty unattached styles - but
* it will almost never be longer than 2 elements.
