Bhikkhu, as I am sure that everyone else here who has benefited from your ready sharing of your vast expertise in typography will agree, I really do appreciate the time and effort you have put into helping each of us learn this new craft. I also understand your frustration with those of us who might not quite "get it" when we read manuals or watch silent videos trying desperately to follow a tiny cursor flitting about the screen in a futile effort to unravel the mysteries of some new software. In the past, I too lost my patience with co-workers who constantly asked me what the Standard Specifications said on a particular matter (apparently, it was easier to ask than it was to read) or complained that my software programs did not function properly. However, it was often those very same "dummies" who could not follow directions who uncovered flaws in my software or revealed ambiguities in the Standard Specifications. So, bear in mind that we dummies are doing our part to make you even better.
I have read the manuals, looked at tutorials and the help topics all of my life but I am a hands-on
sort of fellow and I have to "do it" in order to learn it. So, I'll read about a certain function, what it does and how it does it, but it all remains Greek to me until I actually do it
and see what was actually meant in the function's description. Perhaps one of the most difficult dilemmas to resolve is to replace the expectations, which grew out your own understanding of the descriptions and instructions, with the actuality of the outcome. In other words, you must learn the true meanings of a new language and let go of all that you thought it meant.
Accents over lowercase and Petite Capitals are not moved vertically.
Perhaps a little ambiguity here. Prior to "complete composites" there are no "accents over lowercase", they have yet to be placed. As I understand it, the "placement" is dictated by the accent's own properties. In addition to size, shape and orientation, all of the accents have a defined x and y position in a space shared by every glyph. All of my accents are resting on a guide line @ y=1073 (117 funits above the x-height). None of the low profile accents, or any part of them, extend beyond the CapsHeight while some of the "normal" accents actually do.
After running the PCPU script, all of the low profile accents on the newly minted "small uppercase" glyphs have a y position value of (drum roll please) 410.
One might correctly state that "Accents over lowercase and Petite Capitals have been moved vertically
PS In writing this, I think a relatively easy solution has occurred to me
