	Fix for #162790, by Iwan Wong:

	* gdk/win32/gdkdrawable-win32.c: Implement dashed lines
	correctly. Simplify the interface to render_line_horizontal() and
	render_line_vertical(). Need to draw lines "manually" also on
	NT-based Windowses if we have a dash offset or are drawing
	double-dashed lines.

	* gdk/win32/gdkprivate-win32.h: Keep also the dash offset,
	double-dash flag, and a brush for the background colour (used by
	the odd dashes in the double-dash line style) in the GdkGCWin32
	struct.

	* gdk/win32/gdkgc-win32.c: Set up above new fields.
