LaShonda Hopper fed85a7a53 [Case 4315] ESLint Pass 6 Pt 2 for colpick equality checks (details below).
* Suppressing equality checking issues within color conversion helper functions.
    * These issues are suppressed as opposed to resolved because their resolution causes
      issues with the color picker's understanding of the color it's being set to along with
      the respective hue.  This is likely due to rounding issues; however, it may also be something
      related to the equality operator implicit conversions semantics of JavaScript.  It's something
      that can be looked into later if desired.
          * Bug Steps upon resolving check as opposed to suppressing them:
              - Select a shape entity for example.
              - Note the visual color and actual RGB values for that entity's color upon selection.
              - Click the Color Wheel.
              - Notice the automatic change of the color for the entity when the picker is shown.
                  - If the issue doesn't show itself right away, alter the color for the entity close the
                    picker, and repeat steps 2-3.

* Issue Count reduced from 8 to 1
