In some fonts ascent will be significantly taller than cap height, so a lowercase 'f' will loom above a capital "A." What "size of the text" means is a little fuzzy - is it cap height, ascent, the max of those, or an optic average? The discussion so far seems to be around wanting to size things based on cap height, which is perfectly fine. Another possible use case could be wanting to size things based on ascent, which would require a different unit than "cap height." I just want to be precise about what the current proposal will be providing. Thanks, Alan
