The height dimension value as declared in the patch header may well be less than the "real" height of the composited image. Consequently it is necessary to clamp post pixel ranges when compositing the image to the output buffer.
This is the reason why map drawing in the id tech 1 software renderer can be seen to "overdraw" posts - the wall column drawer is working with post pixel ranges rather than the "logical" height declared in the header.
Todo: Apply this information to texture/material creation.
