Detailed Description

A TGeoBBox that is deliberately slower than a TGeoBBox, by a controllable amount.

The timing harness's negative control: every kernel timed here is also timed against this, and the ratio must exceed a stated factor.

The burn loop is a data dependency on the point, so it cannot be hoisted or constant-folded, and its result is folded into the returned value so it cannot be dropped.
