Returns a line and column at the caret position.
procedure GetCurrentLineCol(out Line, Column: Integer);
(introduced in version 1.7)
Number of lines depends on word-wrapping.
Number of the first line is 1. Number of the leftmost caret position is 1.
Lines in table cells are calculated relative to the beginning of the cell.
Warning: this function contains calculations inside, and it may take some time to execute it
(There is an idea how to make it lightning-fast in future, but it will be implemented later)
This method must be called only when the document is formatted.
