=head1 NAME

A Prima toolkit example

=head1 FEATURES

Tests correct representation of a color created by a combination
of R,G and B components. The Prima::Widget::sizeMin and Prima::Widget::sizeMax
implementation is tested - the Area widget changes its height on a mouse click,
up to the left button and down to the right button. 
Note how Area widget maintains its maximum size when the window gets maximized.
