Additional Draw Widget Improvements

JeffreyThompson2

I've done some additional work on the Custom Draw Widget. This is still mostly @RobertScheitlin__GISP's work. I've also incorporated some inspiration and a bit of code from @AdrienHoff11 to handle point symbol rotation. Reasons for this update:

1. Some visual issues with buttons due to breaking changes circa 1.15.
2. Adding point symbol rotation.
3. ESRI added text support to the official Draw Widget with font options.

What can this widget do?

• From the original version:
  • Draw stuff on a map
    • Points
    • Polylines
    • Freehand Lines*
    • Rectangles
    • Polygons
    • Freehand Polygons*
    • Circles
    • Text
  • Edit vertices
  • Move and delete drawings
  • Edit drawing styles, text value and font style options after drawing*
