Sending input context to XIM server

[Anuradha Ratnaweera <ARatnaweera virtusa com>]

We have successfully created a XIM server which can receive keystrokes
and commit strings to the client.  We are trying to figure out two
issues to proceed forward:

- Does GTK provide callbacks for the XIM server to find out the
characters around the cursor? (so that we can do context dependent
substitutions etc.)

- If yes, (well, this is not exactly a GTK question), how can an XIM
server using IMdkit get to know about them?
