Improve the remote controller pointer and laser

[MortimerGoro]

The remote controller pointer is very big when the widgets are close to the user. Currently we are hiding the pointer for the keyboard because of that.

Ideally we can adjust the scale to make the pointer the same size on any widget. We also can check for alternative designs (sphere?)

We also need to cut the laser geometry based on the hit point distance (e.g. currently the laser overpasses the keyboard)
