This function is in charge of setting the layout that will appear |
| 63 |
in the canvas (row and column ordering). right now it is doing |
| 64 |
its own arrangement based on the mtx structure associated with |
| 65 |
the solver. Eventually it would be much better if the solvers |
| 66 |
provided the display orderings themselves. |
| 67 |
Also this does a 1time query of all the var fixed flags. |
