The intention is that it should be possible to encapsulate all the |

|
non-graphical information about a canvas model using a number of |
| 13 |
|
BlockInstance and LineInstance objects, and no Gaphas objects. It |
| 14 |
|
should be possible to pickle this collection of objects and have everything |
| 15 |
|
that is necessary for passing the model to ASCEND -- this provides the |
| 16 |
|
clean separation of ASCEND-related and Gaphas-releated code, hopefully. |
