Adds Proportional Editing Mode

Functionality similar to Blenders Proportional Edit tool ported to Graphites 2D implementation.

Alt + P to toggle Proportional Editing mode.
Mouse Scroll Up/Down to increase/decrease Influence Radius.
Integrate with GRS tool.

Introduces 8 falloff types:

  1. Constant
  2. Linear
  3. Sharp
  4. Root
  5. Sphere
  6. Smooth
  7. Random
  8. Inverse Square

Closes #2557

A few notes:

  • It should work with G/R/S
  • It should apply to the original drag starting location's range of points, not a continuously updating range of points (see comparison videos below)
  • It should only show the influence circle when dragging, not always when the feature is enabled
