--[[ Element: Castbar
Handles updating and visibility of unit castbars.
Widget
Castbar - A StatusBar to represent spell progress.
Sub-Widgets
.Text - A FontString to represent spell name.
.Icon - A Texture to represent spell icon.
.Time - A FontString to represent spell duration.
.Shield - A Texture to represent if it's possible to interrupt or spell
steal.
.SafeZone - A Texture to represent latency.
Credits
Based upon oUF_Castbar by starlon.
Notes
The default texture will be applied if the UI widget doesn't have a texture or
color defined.
Examples
