[GUI] Show density pushbotton - consider agents positions
Summary
The "show density" push button in the vadere gui visualizes the obstacle density only. The agent-based density is not visualized.
Steps to reproduce
Start the Vadere gui. Run any scenario. Pause the simulation. Set the "show density" option in the GUI.' You will observe that the change of the agent positions do not affect the density map.
Starting point
The agent-based density should be considered. This behavior has already been implemented. Check why the code. Make it executed again.
