The GanttComposite is the workhorse of the GANTT chart. It contains a few public methods available for use, but most of the functionality is private.

There is a serious amount of calculation done in this chart, it's about 80% calculation and 20% drawing. In fact, most of the drawing is delegated to other classes.

A lot of settings method calls are set as class variables, but some are called straight off the settings object. The logic isn't that deep, it's mostly just the over-and-over used variables that get class members. Slow stuff is cached, such as the use of gc.stringExtent(), image rotation and so on. Anything that is slow _should_ be cached as it is a slowdown to the chart. A redraw should be as fast as possible and whenever possible should be specific to certain bounds instead of a full redraw.

This class may not be subclassed.
