haiku/src/servers/app/Window.h
Axel Dörfler bd2509c549 * Desktop::_UpdateFloating() and Desktop::_UpdateSubsetWorkspaces() both
assumed that there was only a single window that was responsible for the
  workspaces of a floating/subset window. Of course, any number of windows
  can make up the workspaces of those. This fixes bug #2506.
* Added a Window::InSubsetWorkspace() method to complement SubsetWorkspaces().
* Minor cleanup.
