Some initial tests for TclTk 8.5.1 on OSX.

10.4/Tiger: the GUI runs and seems to work properly.  NVIZ won't run -  
with Spearfish:

"
nviz elev=elevation.10m

alloc: invalid block: 0x5202b4: 61 0 0

[2]+ Abort trap
"

Even just "nviz --help" gives that alloc error.


10.5/Leopard: won't run at all.  There appears to be some problem  
between Leopard's fontconfig/freetype and TclTk 8.5 (TclTk 8.4 works).

(This is 32bit mode.  In 64bit mode it made it into freetype before  
crashing.)

Unfortunately, I think tcltk/X11 on OSX is forced to used the X11  
freetype/fontconfig build, instead of the one I configure for GRASS  
(my freetype framework).

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly  
what the universe is for and why it is here, it will instantly  
disappear and be replaced by something even more bizarrely  
inexplicable.  There is another theory which states that this has  
already happened.
