--[[ Element: Phasing Icon
Toggles visibility of the phase icon based on the units phasing compared to the
player.
Widget
PhaseIcon - Any UI widget.
Notes
The default phasing 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 PhaseIcon = self:CreateTexture(nil, 'OVERLAY')
PhaseIcon:SetSize(16, 16)
PhaseIcon:SetPoint('TOPLEFT', self)
-- Register it with oUF
self.PhaseIcon = PhaseIcon
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.
