First look at systematically naming setters and queries on the DrawingContext. Setters should have short names as they are used more commonly in client code - for instance lineWidth should set the line width. As querying the line width is legitimate, there is a function getLineWidth - it's expected to be less common in client code, so it gets the longer name. Prefixing both with get- or set- seems a burden although this would be uniform.

Often queries a return a synthetic property which can't be set directly. It seems reasonable to drop the get prefix for these queries as there won't be a corresponding setter.
