build in the backend dir after auto-generating files

	* gdk/makefile.msc : build in the backend dir after
	auto-generating files

	* gdk/win32/gdkfont-win32.c (gdk_font_load) : reimplement
	with code from win32-production-branch.

	*  gdk/win32/gdkwindow-win32.c : set the private->destroyed flag
	before calling DestroyWindow, which indirectly calls
	gdk_window_destroy_notify ()

	(performance patch merged from win32-production-branch)
	* gdk/win32/gdkdrawable-win32.c (gdk_win32_draw_segments):
	Use PatBlt() instead of LineTo() when possible (solid single-pixel pen,
	R2_COPYPEN rop). It is claimed to be much faster.
