[mcclim-devel] Crude multilingual input: CLX meets XKB's body parts.

Dear list, the following is my attempt to get some cyrillic characters
from my keyboard into McCLIM. It is a little crude, and definitely
requires some love before it is in a shape to go in, but it appears to
work for me.
Of course I'm sending the CLX part to a wrong list.
What it does?
1. CLX part
First, it tells CLX to ask the X server to enable XKEYBOARD.
This part wants to be performed conditionally, depending on the
extension's existence, obviously, which I skipped.
Next, it defines keysym -> CL character mappings for the
Cyrillic part of Unicode.
2. McCLIM side
Teach McCLIM to use the extended state bits (those reserved in
the core protocol) in the key-press/release events. This part
is rather agnostic wrt. XKEYBOARD presence, by design of the latter.
Honestly, x-event-to-key-name-and-modifiers appeared like a
low-pass filter to me, and I'm not sure what was the proper way
to approach it. So I just plastered the extended bits over,
without spending much time to understand what I was doing.
Anyway, hopefully this appears more useful than harmful.
regards, Samium Gromoff
