Bug#289078: unreadable bold chars in xbase-fonts -*-clean-medium-r-*-*-*-S-*-*-*-*-*-* fonts (where S <= 100)

[Ken Chase <math@sizone.org>]

Package: xfonts-base
Version: 4.3.0.dfsg.1-1

recently dist-upgraded my unstable system, and got new xfonts-base
package.

In xterm, bold characters in the font 

-schumacher-clean-medium-r-normal--10-100-75-75-c-50-iso646.1991-irv

(which is in /usr/X11R6/lib/X11/fonts/misc/clR5x10.pcf.gz)

and many other fonts like it such as:

-*-clean-medium-r-*-*-*-100-*-*-*-*-*-*   and
-*-clean-medium-r-*-*-*-80-*-*-*-*-*-*	  and
-*-clean-medium-r-*-*-*-60-*-*-*-*-*-*

have totally messed up bold characters (pixels missing from the characters,
more or less unreadable).

(I do have smooth font rendering on my laptop, but it's strange that only
bold is affected for these fonts.)

Im using debian Gnu/linux 2.4.23 custom compile with unstable apt.sources
(off http.us.debian.org) with

ii  xfree86-common 4.3.0.dfsg.1-1 X Window System (XFree86) infrastructure
ii  xserver-common 4.3.0.dfsg.1-1 files and utilities common to all X servers
ii  xserver-xfree8 4.3.0.dfsg.1-1 the XFree86 X server
ii  xfs            4.3.0.dfsg.1-1 X font server
ii  xterm          4.3.0.dfsg.1-1 X terminal emulator

a snapshot of this poor rendering is

http://vinson.sizone.org/~math/busted-xterm-font.png

note the name <@math> in irssi there, is me, bolded, and unreadable.

(this font may look like crap in that snapshot, even the non bold, on a CRT,
but on a good laptop lcd, it is (was?) a great font in 1024x768 for people with
good eyesight and a penchant for a lot of text on screen at once!)
