2001-01-05  Alexander Larsson  <alexl@redhat.com>

	* gdk/linux-fb/gdkdrawable-fb2.c (gdk_fb_drawable_finalize): free
	colormap in here. Sync from X port.
	(gdk_fb_set_colormap): allow the colormap to be NULL if you like.
	Sync from X port.
	(gdk_fb_clip_region): Comment out g_warning about empty clip region.
	This happens now and then, and i don't think it is a bug.
	(gdk_fb_draw_polygon): Correctly add extra point if startpoint
	!= endpoint.
	(gdk_fb_draw_lines): Don't draw dashed lines if line_style is
	GDK_LINE_SOLID.

	* gdk/linux-fb/gdkfont-fb.c: Return bogus GdkFont that has
	some of the fields filled in at least.

	* gdk/linux-fb/miwideline.c: The widths argument to miLineArcI, and
	miLineArcD is no more, remove it from the function definition.
