User Interface :
 * 1) Full Screen Grid (Units aware)
 * 2) Smarter Auto-constraints:
 * 3) Algorithm only considers geometry that is on the screen to increase performance and improve selection
 * 4) Prevent constraint conflicts
 * 5) Hint Lines: horizontal, vertical, perpendicular, tangent constraints?
 * 6) Overhaul of constraint icons by merging into one SoNode
 * 7) Merge into one SoNode to improve performance
 * 8) Remove need for ray pick to increase performance
 * 9) Share texture memory more efficiently.
 * 10) Improve algorithm for preventing overlap
 * 11) Tool Bar for toggling constraint visuals independently
 * 12) Datum Label Improvements:
 * 13) Radius label can be positioned at any angle
 * 14) Remove need for storing in SoImage which isn't needed any more
 * 15) Fix Grid Edge
 * 16) Auto constraints whilst dragging (Point on Point, Point on Line Coincident)?
 * 17) Highlight entities or zoom to over constrained area of sketch
 * 18) Related to part design (transparent support objects)
 * 19) Implement Sketch Plane Feature with introduction of Assembly module
 * 20) Improve Point Selection by implementing new custom node.
 * 21) Construction lines use dashes instead of solid lines.
