SYNOPSIS:
    depth: a common field in Eccet that is used to speed up rendering.

DESCRIPTION:
    Many /renderer/s in Eccet can improve rendering speed dramatically,
    if the depth /field/ is present and filled in appropriately.

    The field has a type of (see /fieldtype/) U8, i.e. an unsigned
    byte with an allowed value range of 0-255 and is called "Depth".

    The field can be allocated using /VOL_ALLOC_DEPTH/, if needed.
