A collection of well known or common attribute keys and methods to apply to an AttributeSet or MutableAttributeSet to get/set the properties in a typesafe manner.

The paragraph attributes form the definition of a paragraph to be rendered. All sizes are specified in points (such as found in postscript), a device independent measure.
