Log Message:
-----------
remove a hard-coded 0.001 constant that has been in here since 1989 (mike,
r3900). the intent seems to be to discard partitions that are behind the ray
start point implying the constant was attempting to capture near-zero or
negative partitions. this should be something below SMALL_FASTF but the
'large' value implies it may be accommodating compound math model-space values
so go with the more dynamic distance tolerance (0.0005) which makes this only
slightly tighter than it was. regression tested/passed on osx.
