Drawing Datatype

This is a DataTypes superclass for structured art and vector drawings.
The archive also includes SVG and IFF DR2D DataTypes which use this superclass.

All use is at your own risk and I do not accept anyvresponsibility for damage or
loss of data incurred through use of any of the contents of the distribution
archive.

If you want to contribute, please email me to be added to the OpenAmiga.org
project.

I've included the public drawingclass header but there is no example source at
this time, other than that at openamiga.org.
