\brief The QwtDynGridLayout class lays out widgets in a grid,
adjusting the number of columns and rows to the current size.
QwtDynGridLayout takes the space it gets, divides it up into rows and
columns, and puts each of the widgets it manages into the correct cell(s).
It lays out as many number of columns as possible (limited by maxCols()).
