How much a moved mesh box is grown, as a share of the magnitudes the f32
transform adds up (the moved box centre's terms, the translation and the
half size): about 8 f32 steps of them, so the corners moved by the f32
matrix stay inside even where large terms cancel (an instance far from the
origin whose geometry is offset back near it).
