   FUNCTION
	This function is used to create an "empty" DiskObject
	structure, which has no image data associated with it.
	Still, all the necessary structures are in place,
	you just have to fill them in.

   INPUTS
	type -- Icon type to create, this must be one of WBDISK,
	    WBDRAWER, WBTOOL, WBPROJECT, WBGARBAGE, WBDEVICE or WBKICK.

   RESULT
	icon -- Pointer to a struct DiskObject or NULL in case of error.
	    You can use IoErr() to retrieve the error code.

   NOTES
	The DiskObject returned by this function will have a zero
	width and height Image in the do_Gadget.GadgetRender member
	and the do_Gadget.Width/do_Gadget.Height members will both
	be 0, too.
