Tcl 7.6/Tk 4.2 bug fixed

[glen e. p. ropella]

Hey guys,

I found the problem with using Tcl/Tk 7.6/4.2.  Unfortunately,
it doesn't fix the raster refresh problem (when occluding the
raster with another window, it doesn't redraw).  So, back to 
the drawing board on that one.  But, if you want to use
Tcl/Tk 7.6/4.2 with Swarm, all you need do is recompile 
libtclobjc, BLT2.1, and Swarm with Tcl/Tk 7.6/4.2 *after* 
making the following changes to BLT (you can cut this diff
out and do a patch < thesediffsinafile, if you want):

As for the raster refreshment.... I'll keep looking. [sigh]
