Visual Aura Range

[scythetwirler]

When an entity that emits an aura is selected or hovered, a circle should be drawn showing it's range. Perhaps this circle could be color coded: Red - Attack modifying Green - Healing Blue - Armour modifying, Loyalty regeneration. Also see #3915.

Any reason why healers have the + aura, while temples still have the standard = line aura?

Replying to fabio:

Any reason why healers have the + aura, while temples still have the standard = line aura?

Because there is a difference between healer range and heal aura range: the healer can only heal one unit in the range, while the healing aura heals every unit in range.

fabio isn't alone, in the end we decided for consistency in ​Phab:D571 We should have more auras textures (then we can reconsider), and ideally an area-texture system (as attempted in delenda est)

In 20622:

Render the range visualization of auras, heal and attack component in a separate RangeOverlayRenderer component instead of abusing Selectable for that.
This also allows non-selectable entities like building previews to cast range visualizations.

In 20624:

Use only one getter for range overlays instead of three to four in the Heal and Auras component.
Move default Heal range visualization texture properties to the template and only display Heal ranges if the template was given.
