--[[ Essentially there are three main types of controls
* Chat Container
This container holds all of the text buffers and tabs.
By default there is a single Chat Container, but players can create more by dragging a tab off of another Chat Container.
* Chat Window
This is the actual text buffer (and anything special like filters in the combat log) where chat messages are added to.
A chat container always contains at least one of these.
* Chat Tab
Each Chat Window has a tab. The tab is the primary place for mouse manipulation.
Dragging a tab pulls off a Chat Window and consequently create a new Chat Container.
Unless the tab is the first tab, then it drags the entire Chat Container.
When the tab is clicked the associated Chat Window is shown.
Lastly, there is the chat system that coordinates dragging across containers, pooling, and so on
