Add parameter telling whether to print warning or not if string isn't

2000-08-20  Tor Lillqvist  <tml@iki.fi>

	* pango/pango-utils.c (pango_parse_*): Add parameter telling
	whether to print warning or not if string isn't recognised. Use
	g_strncasecmp().

	* pango/pango-utils.h: Change prototype accordingly.

	* pango/pangox-fontmap.c
	* pango/pangowin32-fontmap.c: Change calls correspondingly.

	* pango/pangowin32.h:
	* pango/pangowin32.c: Cosmetic changes, dead code removal.

	* pango/pangoft2.h
	* pango/pangoft2-private.h
	* pango/pangoft2.c
	* pango/pangoft2-fontmap.c
	* pango/pangoft2-fontcache.c: New files implementing a FreeType2
	backend. Used only on Win32 so far, but doesn't contain
	Win32-specific code per se, so if somebody wants to try it out on
	X11, too, be my guest.

	It works, more or less, but there are some details still to sort
	out. Performance needs to be improved. Debugging printouts still
	present. Font path currently hardcoded to C:\windows\fonts, heh.

	Owen says he doesn't think it's a good idea to use ths on Win32,
	but I'll try anyway. If it turns out using the native Win32 GDI
	backend is better after all, oh well.

	* pango/makefile.mingw: Delete. Move contents to
	makefile.mingw.in.

	* pango/makefile.mingw.in: New file. Add rules for
	FreeType2 backend. Add FreeType2 CFLAGS and LIBS.

	* pango/Makefile.am: Generate makefile.mingw.
	(EXTRA_DIST): Add FreeType2 backend sources, and
	makefile.mingw{,.in}

	* modules/basic/basic-win32.c: Couple of cosmetic changes.

	* modules/basic/Makefile.am: Generate makefile.mingw.
	(EXTRA_DIST): Add basic-ft2.c, and makefile.mingw{,.in}

	* modules/basic/makefile.mingw: Delete. Move contents to
	makefile.mingw.in.

	* modules/basic/makefile.mingw.in: New file. Add rule for
	basic-ft2. Add FreeType2 CFLAGS and LIBS.

	* examples/viewer-win32.c (read_file): Fix error messages.
	(draw): Get HDC from GDK once for all paragraphs.

	* examples/viewer-ft2.c: New file. The FT_Bitmap (256-level
	bitmap) produced by the FreeType2 backend is copied to the
	GtkLayout window using gdk_draw_gray_image from GdkRGB (!). Yes,
	this is kinda circular dependency between Pango and GTK+.

	* examples/makefile.mingw: Delete. Move contents to
	makefile.mingw.in.

	* examples/makefile.mingw.in: New file. Add rules for
	viewer-ft2. Add FreeType2 CFLAGS and LIBS.

	* examples/Makefile.am: Generate makefile.mingw.
	(EXTRA_DIST): Add viewer-win32.c and viewer-ft2.c, and
	makefile.mingw{,.in}
