I'm just asking for any help i can get regarding how to right-align a string in 
a way that isn't broken by text-scaling. i don't know how to go about it.

i'm only using string-pixel-width because i thought i needed to subtract it from "right" 
in the pixel-width spec, as quoted previously. i don't see how the window or buffer functions can 
help with that that, as i'd have to subtract my string's pixel width from them, so they'd need to 
replace "right", rather than my string width calculation, it seems to me. perhaps you had 
in mind another way to use them, but didn't say.
