-/**
- * IntegerGraphicsState is one of several graphics state
- * implementations. This graphics state is used when the graphics
- * object has simple properties, (coordinate translation only, no
- * transform) and the backend supports integer coordinates (pixel
- * based). For primitive paint operations, this object translates the
- * coordinates and forwards the request to the backend. For requests
- * to draw arbitrary shapes and paths, this object translates the
- * requests to primitive drawing operations supported by the
- * backend. IntegerGraphicsState is meant to support the most common
- * state of an graphics object. The degree of functionality is roughly
- * equivalent with the old java.awt.Graphics API.
