The intention is to utilise this helper class, that was developed for the
scheduler stress testing; but this time, it should access the actual allocated
render buffers to generate the load.
This implies to use buffers of a significant size; it turned out that
the existing implementation was imprecise, insofar it always used full multiples
of the configured buffer size, which defeats the purpose of performing
a precisely calibrated number of calculation steps. As long as the buffer size
would remain comparatively small, this drift does not matter much.
Thus I changed the implementation now to ensure that exactly the calibrated
number of steps is performed, using a modulus to map it to the buffer memory.
Furthermore, I plan to use a random-walk pattern in the worker thread
to select from a collection of pre-established »buffer types«, similar
to what happens in the actual engine
