My mistake, I added this when rebasing and didn't notice that it was a
.glsl file and thus the availability of Math was not confirmed by the
C++ compiler.
A new `Math::division_round_up()` function was added, allowing for easy
and correct computation of integer divisions when the result needs to
be rounded up.
Fixes#80358.
