Patch for OpenBoard v. 1.6.1 by Roberto Puzzanghera roberto.puzzanghera at sagredo.eu
based on this patch http://webdiis.unizar.es/~spd/openboard/index.html.en

More info here https://notes.sagredo.eu/other-contents-186/running-openboard-in-a-window-244.html

OpenBoard runs in fullscreen mode. This seems to prevent the possibility to be recognized
by Google meet as an application to share. This patch gets OpenBoard to optionally run in
a window and solves the issue.

With this patch OB runs in fullscreen mode by default. To run it in a window simply
adjust this option to true in the config file:

RunInWindow=true

On linux the location of the config file is /opt/openboard/etc/OpenBoard.config. A user
can override this file acting in local config file ~/.local/share/OpenBoard/OpenBoardUser.config
