more elementary tooltips via mouse events (imitating parts of javax.swing.ToolTipManager) -- avoid abuse of getToolTipText to produce window as side-effect;
wenzelm [Sat, 16 Mar 2013 12:46:22 +0100] rev 51439
more precise tooltip window size (NB: dimensions are known after layout pack, before making content visible);
more precise margin width based on fractional Pretty.char_width (avoid multiplication of rounding errors);
early initialization of gutter to get proper text area painter size (see also 2585c81d840a);
