Gnats 6066: Prep for Alternative Algorithm for Initial SimObj Placement in "Other" Views
Bug Number: 6066
Release notes (y/n): No
For Release Nums: 7.3

The placement code was broken out from this first method, moved to the 
new 2nd method:

   bool SimWorkspace::addSimObjAtPosition(
      SimObj* obj,
      int newObjX, int newObjY,
      CanvasDefs::CanvasGeometry geom);

   okstat SimWorkspace::assignPosForAllViews_proportionalCanvas(
      SimObj* refObj,
      int newObjX, int newObjY,
      CanvasDefs::CanvasGeometry geom);
