Description
This could help reduce the number of tiles that need to be loaded in the distance at the cost of precision. This could be done by modifying the "screenspace error" value after it's construction. We'd need to ensure that the resulting error value is not less than the initial linear calculation.
Related in part to #1421.

Research direction
Start by locating TilesRenderer's screen-space error construction and review the related discussion in #1421. The issue is complete only when a distance-based error approach is agreed that reduces distant tile loading while never producing a value below the initial linear calculation.
