Customizing brushes for painting tools
You can use the Brushes palette to create brushes, save brushes in
files on disk, modify existing brushes, and delete unwanted brushes.
You can add custom brushes to the list of preset brushes in the pal-
ette. When you exit Canvas, it stores the brush presets. The same set
of brushes are available whether you work with new documents, doc-
uments you created, or documents created by another Canvas user.
