1.5 to 1.6
	1. Removed all use of a seperate bold font. Now uses
	   over-striking exclusively.
	2. Added some more optimizations for drawing speed when
	   the window is re-sized or moved.
        3. Implemented speed ups in screen.c

1.47 to 1.48
	1. Cleaned up re-drawing on expose events, so rxvt only
	   re-draws the newly exposed parts of the screen.
        2. Fixed backspace, which must have broken in 1.45.
	3. Added command line option of iconic startup.

from 1.45 to 1.47
	1. Incorporated improved bsd utmp handling from 
           dperry@ringer.cs.utsa.edu (David Perry)
	2. Fixed a very minor bug where the solid-cursor can leave a
	   a bit of a ghost when you resize the window. Its stupid,
	   but it always bothered me.

from 1.4 to 1.45

	1.  Fixed scrolling error when switching to larger fonts
	2.  Fixed utmp-entry removal for SYSV type systems.
	3.  Icorportated patches for FreeBSD and svr4
