Re: Extent boundaries inconsistent w.r.t. extent properties

But note that there is no *need* to implement anything special here:

the glyphs are always visible if present, then applications code can
arrange to move the glyphs onto some other (storage) property when
they're supposed to be invisible. (This is what preview-latex does.)
This is really a kludge (and, yes, I did write one of the first
examples of this ;-).
But, equally, having begin-glyph-visible and end-glyph-visible
properties would do no harm.
If people don't want to use the start-open and end-open properties
to control the glyph visibility, then we NEED an alternative like
begin-glyph-visible and end-glyph-visible. There's got to be some way
of affecting extent glyph visibility.
