Re: figures not exported properly by ox-latex

im fairly certain that at the time i sent this email, ox-latex was failing
to insert \label and \caption too after images in latex exports (like
ox-html to html exports). but perhaps someone made a change that fixed that.
the fact that ox-latex even inserts \caption and \label tells me that it
was the intention of the maintainer of ox-latex to handle latex blocks
preceded by a `#+caption` as figures. so it would be natural if org
inserted the figure environment itself like it does with images preceded by
`#+caption`. i hope this reasoning does make sense to you?
in ox-html, the function `org-html--wrap-image` is used to wrap an exported
image with a `<figure>` html environment with a caption and label, but it
doesnt happen for me.
after some more digging, i think inserting the `figure` environments
automatically in latex exports may be undesired behavior and it would be
preferred that the user do that themselves in the org document, because
`org-latex--caption/label-string` checks for a `figure` or `listing`
environment apparently, which tells me that the author expected the user to
insert the figure environment themselves. another reason is that the user
may use another, differently environment that accepts a \caption too.
thanks
p.s. sorry i keep hitting the "forward" button instead of the "forward all"
button so you may receive duplicate emails.
