* Do not retrieve the cursor position when the DELETE SURROUNDING callback is called.
When adding characters to an empty text-field, the IMF manager removes first the
pre-edited text and adds the pre-edited text plus the new character.
This patch fixes a flickering issue seen in the virtual keyboard. If the cursor
position is retrieved when the pre-edited text is deleted, the virtual keyboard
is shown with upper case characters and shown again in lower case when the text
is added.
