 GUIViewport:
- - MAJOR TODO - Don't forget to update GUIViewport is to also gets updated when only mesh is dirty!
- - In DX11 it is not possible to clear just a sub-region of a render target
+ - MAJOR TODO - GUIViewport updateRenderElementsInternal only gets called when contents change, but viewport should update even if 
+    only its offset changes (normally that just marks the mesh as modified, which doesn't result in a call to updateRenderElementsInternal)
+
+ Make the drop overlays a transparent gray
+ - Their opacity increases when highlighted
+ - Make their borders use polygon AA (or line AA with a different color)
+
+Figure out how to render the overlay on top of all viewports, even when main window viewport gets rendered first.
+ - I'm guessing the DockManager will require its own Camera (doesn't make sense it would require camera, but it's fairly lightweight so it would be an okay solution)
+ - Then the camera viewport and target change as the dock overlay moves
+ - OR
+ - Have the inner camera viewport render first onto a render target, and then draw the main GUI
+   - This MIGHT be the proper way to do it. Otherwise my game viewport is always limited to whatever format is the main window render target set to.
+ - OR
+ - Render inner camera viewport first, and use stencil to mark the area as non-renderable?
