VISUALWORKS 9.* COMMENT
On Windows (7 through 10), this version of Roassal requires Cairo library version 1.10.2 (provided in VisualWorks 8.3 and after) and does not work with version 1.14.2. Both versions of the Cairo library are provided in VisualWorks 8.3.1 and after, with the relevant ExternalInterface class definition data set to see the older version. With a small code change, a knowledgeable user can move to the new version and load a later compatible version of Roassal from the Cincom Open repository, should they so wish.
Roassal2 was developed from Roassal, which was in turn developed from Mondrian. This contains the functional code for Roassal2 in VisualWorks.
