Fix confusing argument value to fl_measure() in tooltip handling.

The argument 'draw_symbols' was inconsistently set with the intended
tooltip label alignment. This was confusing, but didn't do any harm
since the value was != 0 anyway.

Also added the 'image' and 'draw_symbols' argument to fl_draw() call.
Defined static constant draw_symbols_ for potential later inclusion in
Fl_Tooltip class and code clarification.
