I agree, but sometimes we don't get to choose :-)

OK. Probably getting in over my head (hence my original post) but I  
will see what I can do. Given the issue of usefulness in general as  
discussed above, perhaps this kind of thing is best kept as a private  
build?

In toying around with this since I first brought it up, I note that  
simply changing the size of 'have' to [34816] seems sufficient (that  
is: FreeType will open and display the font data). But as I expressed  
originally, I'm not sure what else I'd be breaking by doing this.


Thanks a lot, I appreciate your feedback.
