I'm including the scaled files for my resized skin, to let you evaluate it...
I decided to abandon the idea of displaying the GIF file and drawing the scaled boxes over that; it was just so much work, and I knew I could complete the basic scaling work in a couple of hours.
I still need to update the readme.md file for this project, to describe how to utilize it.
As I noted previously, this is mainly designed for resizing existing skins; other design goals may require further modifications to the program.
Look it over and provide any comments that you have... it *appears* to be working well, though there may be testing modes that I'm not aware of.
