In depth
The level whose image is IRRADIANCE_EDGE across. For the default 256 edge that is level 5, and
the chain stops there rather than carrying unread levels above it — texStorage3D takes a
level count, so the three that would hold sixteen, four and one texel are never created. Six
levels, 87,360 texels, 683 KB a layer at half float.
