this is why EFL doesn't have support. i'd have to write it all, OR use pango...
and pango, last i looked, was not light on overhead, so as a matter of
performance doing it the simple way its done now handles things for most people
(who buy/use devices or linux systems as most people tend to speak a
left-to-right friendly language). i have seen remarkably little interest in
things like left-to-right languages over the years, and as there isn't a lot of
demand and i don't actually speak any of these (i just speak european languages
- a few of them, and east-asian languages), i just have never had it come up
high enough on the list of things to do.. to ever do it. at least all the text
internals are utf8 so... it's possible to do this without breakages...
