9 e275f77943 Define EMULATE_GDKFONT. Add extra pango_font stuff to GfkFontPrivate. 
2001-01-19    <alexl@redhat.com>

	* gdk/linux-fb/gdkprivate-fb.h:
	Define EMULATE_GDKFONT.
	Add extra pango_font stuff to GfkFontPrivate.

	* gdk/linux-fb/gdkdrawable-fb2.c:
	* gdk/linux-fb/gdkfont-fb.c:
	If EMULATE_GDKFONT defined, implement a slow lame GdkFont
	emulation using PangoFont.
