Missing the point. You stated that you made a change, gave the code, but 
never actually said how or why you are using it. This is sadly one of the 
reasons why some great ideas never see the light of day. It is not enough 
to toss code into people's laps and say, "Here is something I did. Maybe 
someone will find it useful." You also have to tell them what the heck 
you thought it was useful for. You didn't do that until someone a great 
deal brighter than me questioned 'how' you did it and suggested 
transparency.

Now, there is what I meant. A wonderful example. Now someone can look at 
it as say, "Heh, that's something I could really use. Where is the 
patch?" I may even use it myself some time. I have a program I designed a 
while back involving a GPS locations database, but always wanted to put a 
map in with it. The problem was a) I didn't want a 1G files, which I 
couldn't put on a CD anyway and b) I couldn't find any smaller version 
that where not pure junk. Being able to take a 1G file of the place I 
want and render a series of smaller images that are easier to load would 
be very helpful. Now I just need to find the damn map I need to do it 
with... lol

Of course I also don't have, want to, or plan to compile a patch myself, 
so unless this does find its way into MegaPOV or something, I probably 
still won't use it. My philosophy is that if you don't understand even 
10% of how a program works, don't screw with any of it yourself. ;) lol
