--[[ Element: Raid Icon
Handles updating and toggles visibility of raid target icons.
Widget
RaidIcon - A Texture used to display the raid target icon.
Notes
This element updates by changing the texture.
The default raid icons will be used if the UI widget is a texture and doesn't
have a texture or color defined.
Examples
-- Position and size
local RaidIcon = self:CreateTexture(nil, 'OVERLAY')
RaidIcon:SetSize(16, 16)
RaidIcon:SetPoint('TOPRIGHT', self)
-- Register it with oUF
self.RaidIcon = RaidIcon
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.
