/**
|
|
* \file stack-tracker.h Track stacking order for compositor
|
|
*
|
|
* MetaStackTracker maintains the most accurate view we have at a
|
|
* given point of time of the ordering of the children of the root
|
|
* window (including override-redirect windows.) This is used to order
|
|
* the windows when the compositor draws them.
|
|
*
|
|
* By contrast, MetaStack is responsible for keeping track of how we
|
|
* think that windows *should* be ordered. For windows we manage
|
|
* (non-override-redirect windows), the two stacking orders will be
|
|
* the same.
