Display glitch with bolodd2 and bolodd3?

Nice catch - that might have been hard to find if you hadn't noticed
the other places that the thick pen size is used.  I was obviously far
from the bug, if I was browsing through tkconq.tcl rather than the X11
calls in the C code (which is my vague recollection of where I had
looked for it before).
