This was an almost-complete rewrite of the script. The original script was designed to do something very basic, and as a result, every additional feature led to an exponential increase in the code. More code, more potential for errors -- the v1.1 code had about 4,600 lines of code, the v1.2 has about 1,800 to accomplish the same tasks, plus some. So, I rewrote about 90% of the code to be faster and to allow for future expansion. If you note any bugs, please let me know.
Changes from v1.1
1. Per ClassicalStamps' request, added ability to general Internal frames (style similar to SG New Imperial Album)
2. Fixed numerous small bugs and placement errors. Math is hard.
Here's a sample of what the Internal frame style looks like compared to the full size of a stamp. The frame doesn't generate in the red color -- I changed it so it was more visible in the pic.

On the page, it should look something like this.

For the next version, I'm working on a couple things. Perhaps the most useful is preset styles.
I'm attempting to modify the Settings spreadsheet so you can select from a list of standard frame designs. For example -- if you like boxes in the SG New Imperial style (Internal frame with simply a catalog number below the stamp), you'll be able to click a button and automatically fill the settings blanks with the proper settings. Ditto for Mystic style, etc.
Mystic styleFor example, these are actual boxes from a Lighthouse page.
Lighthouse sampleAnd these is from a preset designed to replicate the Lighthouse style.
Lighthouse-style boxesThis should prove helpful for those who use different designs on different countries' pages.
If anyone is interested in having a particular preset, you can really help me out. If you've used the script to generate a standard style, send me the settings you use and I'll see if I can include them. If you haven't used the script but you use a particular style of page, send me a high-quality scan of the stamp boxes with and without a stamp in the box (and if possible, with measurements in mm of the stamp and box so I can set the padding/margins). I can get close based on a good quality scan.
As usual, comments and suggestions are appreciated.
