NAME
	RemBob -- Macro to remove a Bob from the gel list.

   SYNOPSIS
	RemBob(bob)

	RemBob(struct Bob *);

   FUNCTION
	Marks a Bob as no-longer-required.  The gels internal code then
	removes the Bob from the list of active gels the next time
	DrawGList is executed. This is implemented as a macro.
	If the user is double-buffering the Bob, it could take two
	calls to DrawGList before the Bob actually disappears from
	the RastPort.

   INPUTS
	Bob = pointer to the Bob to be removed
