It might be that some MegaPOV code counts from 1 to image height. Make sure
that when MegaPOV calls MacFile_ReadLine the parameter line_number starts
with 0, not 1. Then fix the MegaPOV code (not the sysmacpict code as a 0
base is required for it to work with other POV-Ray code). You do not notice
this problem with other formats because PICT images cannot be loaded line by
line and therefore need a working line counter, while other formats may not
even use it.
