There are (at least) two problems.

ace_outer is not rtl even if the url has "?rtl=true"

ep_cursortrace creates a hidden span to calculate the location of the cursor
the span is copied from ace_inner, which has "dir=rtl", to ace_outer, which doesn't
so we have to add "dir=rtl" to somewhere in ace_outer
- if we add "dir=rtl" to ace_outer, we probably have to modify css too

ep_cursortrace uses too many "left"

it assumes that the cursor position is defined by "top" and "left"
so we have to switch the code from top-left to top-right according to the direction

Both are quite a lot of work.
