[Mono-winforms-list] RFC on winforms / XIM clientWindow fixage

[Atsushi Eno]

Hi,

I'm posting it as I've been stuck with this issue for couple of days and
I still don't have a fix.

Now I'm trying to fix XIM stuff to show up IM engine UI. Currently only
scim works (I tried scim-anthy). Everything else (as far as I tried,
iiimx/atokx3 and kinput2) do not work.

It is (to my understanding) due to incorrect use of "client window" of the
input context (XIC). I fixed this issue with the patch [*1] but
it caused (or exposed) some regressions [*2][*3].

My guess is that there are some issues around X event filtering (as
XplatUIX11.WaitForHwndMessage does not finish) but I don't know how it
could be fixed.

I'll continue working on this issue but any help would be appreciated.
