vertices instead of lines.) On large maps, this can result in a very
significant speed up. (In one particular map, ZDBSP had previously
spent 40% of its time just scanning through all the vertices in the
map. Now the time it spends finding vertices is immeasurable. Now 68%
of its time on that map is spent inside ClassifyLine--because that
routine is called more than 16 million times, which suggests that even
a minor speedup in that routine should have a big impact--if I could
just think of how that might happen.) On small maps, this won't make
much of a difference, because the number of vertices to search was so
small to begin with.
