ToolWindowManager

ToolWindowManager is a Qt based tool window manager. This allows Qt projects to use docking functionality similar to QDockWidget, but since it's a separate component it's easier to customise and extend and so has a number of improvements over the built-in docking system.

This is a fork from https://github.com/riateche/toolwindowmanager, specifically from 5244be3f9ac680ac568a6eff8156a520ce08ecf1 where the license is clearly MIT. After that point there was a re-implementation that may have relicensed under LGPL and the author has not clarified.

Also this fork contains a number of changes and improvements to make it useful for RenderDoc and perhaps other projects. Notable highlights:

Additional customisability like arbitrary data tagged with saved states, callbacks to check before closing, and allowing/disallowing tab reorder or float windows
Fixes for having multiple nested TWMs
Render a preview overlay for drop locations
Use hotspots icons and specific locations to determine drop sites, not the old 'cycle through suggestions' method
Allow dragging/dropping whole floating windows together
