** Fixes bug #303877.
2007-08-23 Matthew Barnes <mbarnes@redhat.com> ** Fixes bug #303877. * e-cell-text.c: (update_im_cursor_locations): New function. Set the cursor location to IMContext for candidate window. (e_cell_text_get_cursor_locations): New function. Get the current cursor locations in root canvas. (e_cell_text_preedit_changed_cb): set the preedit cursor position to preedit_pos. (layout_with_preedit): call update_im_cursor_locations in the tail. Patch by Hiroyuki Ikezone. svn path=/trunk/; revision=34082
