Sorry I didn't realize it is there already.

I looked at Hidetoshi's code, it seems to me that he set im cursor
location after every gtk_text_layout_draw().  I am trying to set
im cursor location only when the cursor change position, which
I figured the position change will happen at a. button release
event; b. pend_cursor_blink().

I am trying to set im cursor location only when the cursor change
position, which I figured the position change will happen at
a. button release event; b. key in (pend_cursor_blink()).

The only time which I have trouble with is when the TextView
is first created, I don't know how to call
im_context_set_cursor_location().
So the initial im context cursor position is always at a default
location.
