Viewport's "Object Name Label" Improvements

In Object properties, you can enable the name of the object to appear in the viewport. Currently, this call-out floats very near the object center, and is just text, making it hard to read for numerous reasons.

I recommend the following improvements:

• Control font size
• Control the label's position relative to an anchor, which could be:
  • The median point of a vertex group (object must use the group)
  • The median point of the entire mesh
  • The object pivot point
• Control label's distance and x/y offset from the anchor point
• Control label's alignment: left/right/top/bottom relative to anchor (currently label is always on the right)
• Give the label a contrasting background & border
• Optional runner line from the anchor to the label (enabled by default)
• Control the label's colors: background, border, text, runner
• Label Groups:
  • Would appear in the Object Data panel like Vertex Groups do, just for deleting/renaming purposes.
  • When setting up the label for an object, you can select from this list.
• Use these improvements to craft a nicer-looking default label style.

Extras:

• Ability to select an object by clicking its label
• Label's runner and border would match the object's active border color, even when not active
• Culling depth / X-Ray options (per Label Group).
• Interacts well with Bone appearance options (colors, curves, etc)
