Updating camera near/far values to match new world rendering scale
Updating camera near/far values to match new world rendering scale

Without reducing the near value, some scene elements that should be
visible at a given distance become no longer visible. The far value
technically doesn't need to be reduced, but doing it anyway because
even the new value should be much larger than actually needed.

These values are roughly reduced by 12 to match the new scene scale,
but not exactly in favor of rounder numbers.
