Investigate adding an optional tile mapper to the capturer

[jackjansen]

Right now, with 4 cameras we get 15 tiles. That's overkill, as most will be empty. It's better to have 9 tiles (8 compass directions, and one "other" that combines the rest of the tiles).

The "other" tile could have a direction of "up" or "down" that should work fine with the selection algorithm.

Integrating the tilemapper turns out to be more work, because we have to recompute the new tileconfig and this is not trivial.

Also, it should ideally be done at the source, so in the native code and when we create the tiled point clouds (so we don't pay an extra performance penalty).

Leaving this for now.
