Started reintegrating uiWindow on macOS. I didn't think the implData variable naming through... Also made uiWindow a mere typedef to uiControl; I'll need to copy the handle logic from Windows to make this robust, or something to that effect...

-`uiWindow` is an opaque `uiControl` type that represents a window.
+`uiWindow` is a `uiControl` that represents a window.
 
 Windows are the highest level of a control hierarchy that is visibile on screen. All controls that are current visible are contained within a `uiWindow`, and it is the size and position of the window that ultimately decides their size and position (though a control's minimum size may contribute to this). Windows also have titles, which are used to identify the window to the user.
