The input widget's cursor should be aware of the keyboard layout we're 
currently using, and whether we're about to input RTL. When we're in an 
RTL-language keyboard layout, the cursor should have the indicator arrow 
pointing to the left, to reflect the input directionality. Similarily, 
switching to an LTR-language (e.g. English) should make the indicator 
arrow pointing to the right.

This would also eliminate the need for the "double cursor", at places 
where GTK+ cannot otherwise know on what side of the string the input 
would continue (Hebrew will attach to the left of the existing Hebrew 
string, but if we'll enter an English string suddenly, it'll be added to 
the right of the Hebrew string -- in strong-LTR aligned BiDi of course). 
The prediction about where the next input would be added would be based 
on the current keyboard layout.

Since with proper Xkb keyboard maps we can know the current group's Name, 
we can use this name to decide whether the current group (in multigroup 
maps, such as an English-Hebrew one) is for inputing an RTL language 
(such as Hebrew or Arabic) or an LTR language (such as English).

This should require standardization of the group names used in the Xkb 
maps distributed with XFree86. Group names are supposed to be named after 
the language, not the country. And even then, "Israelian" isn't quite 
proper English (supposed to be "Israeli" -- or in our case, "Hebrew").
