[Coco] Graphics on NitrOS9 Level 1 v3.3.0 (CoCo 1)

[David Ladd]

So here is a update on the issue.

So far the progress is slowly moving along on this.

level1/vtio now seems to properly load GrfDrv and is no longer eating
display codes that should be sent to level1/GrfDrv.

Issues yet to fix is crashes related to level1/GrfDrv in how it handles the
Set Point and Erase Point codes ($18 and $19).

These fixes will come as time permits and possible solutions are found.
