Tor Lillqvist e96a41be45 gdk/win32/gdkprivate-win32.h Rename all global variables and functions to 
2002-11-12  Tor Lillqvist  <tml@iki.fi>

	* gdk/win32/gdkprivate-win32.h
	* gdk/win32/*.c: Rename all global variables and functions to
	start with underscore.

	Merge from stable:

	More work on the Win32 backend. The cause of some scrolling
	problems was that SetWindowPos() and ScrollWindowEx() don't blit
	those parts of the window they think are invalid. As we didn't
	keep Windows's update region in synch with GDK's, Windows thought
	those areas that in fact had been updated were invalid. Calling
	ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to
	be an elegant and efficient solution, removing from Windows's
	update region those areas we are about to repaint proactively.

	In some cases garbage leftover values were used for the clip
	origin in GdkGCWin32. This showed up as odd blank areas around the
	pixmaps included in the Text Widget in gtk-demo.

	Having the clip region either as a GdkRegion or a HRGN in
	GdkGCWin32 was unnecessary, it's better to just use a HRGN.

	The translation and antiexpose queue handling in
	gdkgeometry-win32.c seems unnecessary (and not implementable in
	the same way as on X11 anyway, no serial numbers) on Windows,
	ifdeffed out.

	Don't (try to) do guffaw scrolling as there is no static window
	gravity on Windows. Guffaw scrolling would be unnecessary anyway,
	as there is the ScrollWindow() API. This improves the behaviour of
	the Text Widget demo in gtk-demo a lot. But I have no idea how the
	lack of static win gravity should be handled in other places where
	the X11 code uses it. Especially _gdk_window_move_resize_child().

	There is still some problem in expose handling. By moving an
	obscuring window back and forth over testgtk's main window, for
	instance, every now and then you typically get narrow vertical or
	horizontal strips of pixels that haven't been properly redrawn
	after being exposed. A fencepost error somewhere?

	Otherwise, all of testgtk and gtk-demo except "big windows" now
	seem to work pretty well.

	Bug #79720 should be fixed now.

	* gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string,
	gdk_win32_print_paletteentries, gdk_win32_print_system_palette,
	gdk_win32_print_hpalette)
	* gdk/win32/gdkdrawable-win32.c (gdk_win32_drawable_description)
	* gdk/win32/gdkevents-win32.c (gdk_win32_message_name):
	Move all debugging helper functions to gdkmain-win32.c.

	* gdk/win32/gdkdrawable-win32.c (_gdk_win32_draw_tiles):
	Rewrite. Make static. Must take tile origin parameters, too.

	(gdk_win32_draw_rectangle): Pass the tile/stipple origin to
	_gdk_win32_draw_tiles(). Remove #if 0 code.

	(blit_inside_window): Don't call ScrollDC(), that didn't work at
	all like I thought. A simple call to BitBlt() is enough.

	* gdk/win32/gdkevents-win32.c (gdk_event_translate) Remove unused
	latin_locale_loaded variable.

	(_gdk_win32_get_next_tick): New function. Used to make sure
	timestamps of events are always increasing, both in events
	generated from the window procedure and in events gotten via
	PeekMessage(). Not sure whether this is actually useful, but it
	seemed as a good idea.

	(real_window_procedure): Don't use a local GdkEventPrivate
	variable. Don't attempt any compression of configure or expose
	events here, handled elsewhere.

	(erase_background): Accumulate window offsets when traversing up
	the parent chain for GDK_PARENT_RELATIVE_BG, in order to get
	correct alignment of background pixmaps. Don't fill with
	BLACK_BRUSH if GDK_NO_BG.

	(gdk_event_get_graphics_expose): A bit more verbose debugging output.

	(gdk_event_translate): Use _gdk_win32_get_next_tick(). In the
	WM_PAINT handler, don't check for empty update rect. When we get a
	WM_PAINT, the update region isn't empty. And if it for some
	strange reason is, that will be handled later anyway. Call
	GetUpdateRgn() before calling BeginPaint() and EndPaint() (which
	empty the update region).

	* gdk/win32/gdkdnd-win32.c
	* gdk/win32/gdkinput-win32.c:
	Use _gdk_win32_get_next_tick().

	* gdk/win32/gdkfont-win32.c: Use %p to print HFONTs.

	(gdk_text_size): Remove, unused.

	* gdk/win32/gdkgc-win32.c:  Set clip origins to zero
	when appropriate.

	(gdk_gc_copy): Increase refcount on colormap if present.

	(gdk_win32_hdc_get): Handle just hcliprgn. If we have a stipple,
	combine it with clip region after selecting into the DC.

	(_gdk_win32_bitmap_to_hrgn): Rename from _gdk_win32_bitmap_to_region.

	(_gdk_win3_gdkregion_to_hrgn): New function, code snippet
	extracted from gdk_win32_hdc_get().

	* gdk/win32/gdkgeometry-win32.c: Ifdef out the translate_queue
	handling.

	(gdk_window_copy_area_scroll): Increase clipRect to avoid
	ScrollWindowEx() not scrolling pixels it thinks are invalid.
	Scroll also children with the ScrollWindowEx() call. No need to
	call gdk_window_move() on the children.

	(gdk_window_scroll): Don't do guffaw scrolling.

	(gdk_window_compute_position): Fix typo, used win32_y where x was
	intended.

	(gdk_window_premove, gdk_window_postmove,
	gdk_window_clip_changed): Add debugging output.

	(_gdk_windowing_window_queue_antiexpose): Just call ValidateRgn()
	on the region.

	(_gdk_window_process_expose): No use for the serial number
	parameter now. Instead of a rectangle, take a region parameter, as
	Windows gives us one in WM_PAINT.

	* gdk/win32/gdkmain-win32.c (_gdk_win32_lbstyle_to_string,
	_gdk_win32_pstype_to_string, _gdk_win32_psstyle_to_string,
	_gdk_win32_psendcap_to_string, _gdk_win32_psjoin_to_string,
	_gdk_win32_rect_to_string, _gdk_win32_gdkrectangle_to_string,
	_gdk_win32_gdkregion_to_string): New debugging functions.

	(static_printf): Helper function for the above. sprintfs into a
	static circular buffer, return value should be used "soon".

	* gdk/win32/gdkwindow-win32.c (gdk_propagate_shapes): Plug memory
	leak, free list after use.

	(gdk_window_gravity_works): Remove, we know that there is no such
	thing on Windows.

	(gdk_window_set_static_bit_gravity,
	gdk_window_set_static_win_gravity): Ditto, remove, they didn't do
	anything anyway.

	(_gdk_windowing_window_init, gdk_window_foreign_new): Call
	_gdk_window_init_position() like in the X11 backend.

	(gdk_window_reparent): Don't call the now nonexistent
	gdk_window_set_static_win_gravity(). No idea what should be done
	instead.

	(gdk_window_get_geometry): The returned x and y should be relative
	to parent. Used to be always zero..

	(gdk_window_set_static_gravities): Return FALSE if trying to set
	static gravity.

	* gdk/win32/gdkprivate-win32.h: Drop the clip_region field from
	GdkGCWin32. Only use the HRGN hcliprgn. Declare new
	functions.

	* gdk/win32/*.c: Use new debugging functions.

	* gdk/win32/rc/gdk.rc.in: Update copyright year.
