So, while I was searching my hard drives for little routines and utilities to add to my new little Github Toolbox project, I came across these old routines -- RoundRectFill and thickCircle. I don't know who the original author of these were; I don't think I wrote them, but the drive they were on was probably 5 to 10 years old and dated all the way back to the days of Galleon's Forums (.net?), and back when we were all chatting and talking over on the freenode IRC chat channels. (MY original SBot which ran via freenode was in the same folders, which is what helps me date how old these things are! LOL!)
My best guess is STxATxIC or perhaps vince helped create these originally. If anyone knows for certain who the original author of RoundRectFill and thickCircle are, let me know and I'll be certain to add their names to the routines to give them credit for their work.
(If you notice, I didn't list RoundRect as being unknown. That's simple -- I wrote it this evening to go with the filled version. If there was ever an original RoundRect routine somewhere, I didn't save it, so the one here is one I derived myself. It's no mystery code!
)Anyways, I thought I'd share these here to see if anyone knows for certain who the original authors were, before just tossing them all slappy-happy into my toolbox. Kindly speak up if they were yours. Heck, they might've even been mine -- though it's been so long, I certainly don't remember them! LOL! Solve the mystery, if you have information on "Where the heck did those come from?"
