--[[ Element: Quest Icon
Handles updating and toggles visibility based upon the units connection to a
quest.
Widget
QuestIcon - Any UI widget.
Notes
The default quest icon will be used if the UI widget is a texture and doesn't
have a texture or color defined.
Examples
-- Position and size
local QuestIcon = self:CreateTexture(nil, 'OVERLAY')
QuestIcon:SetSize(16, 16)
QuestIcon:SetPoint('TOPRIGHT', self)
-- Register it with oUF
self.QuestIcon = QuestIcon
Hooks
Override(self) - Used to completely override the internal update function.
Removing the table key entry will make the element fall-back
to its internal function again.
