- Made some changes to the way I check for deleting instances. - Added a new bounding box check for painting grass. - Made GetNewGrassBounds return a bounding box instead of our parameters - Added new Expand method to bounding box util - Added instance radius check and instance brush check to project form for possible future instance types (Props) - Added grass brush gizmo - Updated gui for grass instance batch panel - Fixed bug with GoToPosition (with bounds)
