improving UI of FPS counter
The FPS counter shows the frame rate based on a time-stamp history and is located in the compositor's HUDLayer.
This change includes:
- moving to top right corner
- plotting the graph's X-axis based on time between frames
- measuring min/max value instead of standard deviation
- showing histogram of time spent in each value
- scaling to the max value in case of very high fps (disabled vsync)
