and proceeding upward (unless the depth is negative) and to the right (unless the
width is negative). The end position after this operation will be the specified position.

If the width and depth are both zero, no segment will be appended, but the current
position will still be updated.
dlpdfpathaddclose
This method accepts no operands. It will append to the path a close path operator
and leave the current position as the first specified position in the path.
dlpdfpathsetmatrix
This method accepts a pointer to a path and a pointer to a matrix. The specified
matrix will be concatenated (i.e. applied) to the matrix of each container in which this
path is drawn, affecting all on the current path. This allows the user complete and
flexible control of the shape drawn by the path. If the pointer to the path or the
matrix is NULL, a genErrBadParm exception will be raised.
dlpdfmatrixrotate
This function will modify the specified matrix so as to effect counter-clockwise
rotation of any marks drawn via this matrix. Angle is an angle in degrees and
fractions of degrees.
Patterns
Patterns are created in the context of a document, and represented by the structure
DLPDFPATTERN. They contain a content block, whose contents become one tile of the
