Style - style container Theme - parent for all styles

Synopsis

import dcanvas.widgets.styles;

Recent changes: Dimensions like fontSize, padding, margins, min/max width and height can be specified in points, e.g. minWidth = "3pt" margins="1pt,2pt,1pt,2pt" % for font size, based on parent font size, e.g. fontSize="120.5%" means parentStyle.fontSize * 120.5 / 100.0;
