tableKMFL.odg: helper document to demonstrate the problem.

KMFL is an ibux linux keyboarding solution that converts keyboard entry (like
;;~a into ä̃ ) by using accessibility calls to delete the previous characters.
This has stopped working in Draw in LO 6.2 - now the cursor frequently jumps
around when GTK calls to delete/replace the characters.

Information on installing kmfl can be found in bug 91641 comment 0 and comment
1.

Steps:
1.) With ibus kmfl configured with GE.kmn, open the attached document
2.) Click in the first text box and enter "simple" there.
3.) Click in the yellow table square, and type ;;~a

Result:
the ;;~ composing characters are left in the yellow square, and the composed ä̃
is the first character in the textbox.

I imagine this might have implications for CJK keyboarding solutions based on
ibus as well, but have no proof of that.
