Classes that provide support for vector graphics painting.
Wt provides a vector graphics painting system, which depending on the browser support, uses one of four different methods to paint the graphics (inline SVG, inline VML, HTML 5 <canvas> or a raster image). Vector graphics has as benefit a lower bandwidth usage compared to raster images, indepedent of the image size. To use the paint system, you need to specialize WPaintedWidget and use a WPainter to paint the contents of the widget inside its WPaintedWidget::paintEvent().
In addition, a PDF backend is included in the library, which can be used to make a PDF version of a painting, or to embed a painting in a PDF document.
To use inline SVG, you need to enable xhtml support in your configuration file by enabling send-xhtml-mimetype, see 10.2 General application settings (wt_config.xml).
