Improve fps_overlay example (#15739)

Browse source 
This PR improves the `fps_overlay` example by adding:

1. The ability to increase the overlay font size (previously, only
decreasing the size was supported).
2. A toggle for overlay color between red and green (previously, it only
changed from green to red without toggling back).
