[A12n-Collab] Combining diacritics, type them as if they were dead keys? (GTK+, X.Org)

[Simos Xenitellis <simos.lists@xxxxxxxxxxxxxx>]

Hi All,

At the moment, when one types combining diacritics in X.Org (as in 
Linux), they type
<letter> <combining diacritic 1> <combining diacritic 2> ...

This is different from the case when you have dead keys:

<dead key 1> <dead key 2> ... <letter>

There has been interest by users to be able to type in the order:

<combining diacritic> <letter>

or, in the general case,

<combining diacritic 1> <combining diacritic 2> ... <letter>

Is there interest to go for this case where the letter is typed last?
It would be good to get some input on this, because if we go for it, it 
would affect all layouts.
Currently, at least the us (US), cd (Congo), ng (Nigeria), sy (Syria) 
layouts use Combining diacritics.
Cheers,
Simos
