gtk/gdk/win32/gdkdrawable-win32.c
Tor Lillqvist fda3e29611 Reflect recent renamings and removals of functions. 
2002-11-15  Tor Lillqvist  <tml@iki.fi>

	* gdk/gdk.def: Reflect recent renamings and removals of functions.

	Merge from stable:

	Start implementing all fill styles (i.e. tiled, stippled, and
	opaque stippled in addition to the plain solid style) in the Win32
	backend in an elegant and generic way. For now only did the
	draw_rectangle() and draw_glyphs() methods. The rest will
	follow. Previously some of the drawing methods implemented opaque
	stippling, but not tiles or non-opaque stippling.

	Seems to work fine, now the check marks show up in check buttons,
	the stippled background and stippled text in gtk-demo's Text
	Widget look as they should, and GtkText's line wrap arrow shows
	correctly instead of an ugly rectangle. [This refers to the stable
	branch, haven't actually checked HEAD.]

	The implementation does do a lot of pixmap handling and blitting
	back and forth, especially on Win9x. But performance is hopefully
	not an issue. I don't think many applications do a lot of tiled or
	stippled drawing.

	* gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that
	calls a GDI function and prints a warning if it failed. Also
	API_CALL for non-GDI calls. Cleans all the the if (!BlaBla())
	WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written
	GDI_CALL (BlaBla, ()). Declare new functions.

	* gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places.

	(generic_draw): New function that handles all the blitting
	necessary to implement tiles and stipples. A function that
	actually draws stuff is passed as a parameter to
	generic_draw(). If the fill style is solid, it is called
	directly, to draw on the destination drawable. Otherwise it is
	called to draw on a temporary mask bitmap, which then is used in
	blitting operations. The tiles and/or stipples are rendered into
	another temporary pixmap. If MaskBlt() is available (on NT/2k/XP),
	it is used, otherwise a sequence of BitBlt() is used to do the
	final composition onto the destination drawable.

	(draw_tiles_lowlevel, draw_tiles): Some renaming and code
	reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable().

	(rop2_to_rop3): New function, does binary->ternary rop mapping.

	(blit_from_pixmap, blit_inside_window, blit_from_window): Use
	rop2_to_rop3(). Previously used SRCCOPY always...

	(draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs,
	gdk_win32_draw_glyphs): Split functionality into two functions,
	with generic_draw() doing its magic inbetween.

	* gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it
	was ifdeffed out and wouldn't have done anything even if
	enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't
	have any effect any more anyway after all the changes GTK+ has
	gone through in the last years. Remove some #if 0 code.

	* gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field
	to NULL in case a GC is copied while it has a Windows DC active.

	* gdk/win32/gdkprivate-win32.h
	* gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc.

	* gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc
	option. If there is a PRETEND_WIN9X envvar, set windows_version as
	if on Win9x.

	* gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new,
	gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't
	used or exported. Make a bit more like the X11 version. Hopefully
	I didn't break the fragile palettized display ("pseudocolor")
	code.

	* gdk/win32/gdkgc-win32.c: Various debugging output improvements.

	(predraw_set_foreground): Check whether
	tile/stipple origins are valid when calling SetBrushOrgEx().

	(gdk_win32_hdc_get): Ifdef out code that tries to handle the
	stipple by converting it into a region, and combining the clip
	region with that. A stipple shouldn't work like that, it should
	replicate in x and y directions. Stipples are now handled by
	generic_draw() in gdkdrawable-win32.c.

	* gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string,
	gdk_win32_rop2_to_string): New debugging functions.

	(gdk_win32_print_dc): Print also DC's rop2 and text color.
