Removed unused arguments from gdk_fb_drawable_get_pixel().

2000-11-20  Alexander Larsson  <alla@lysator.liu.se>

	* gdk/linux-fb/gdkdrawable-fb2.c:
	Removed unused arguments from gdk_fb_drawable_get_pixel().

	* gdk/linux-fb/gdkinput-ps2.c (handle_input_ps2):
	Renamed fidur specific mouse packet data in MouseDevice to
	generic. Used it in ps2 mouse handling code to avoid blocking
	reads.
