- Fixed the OrgSectorMap generation in FLevel::RemoveExtraSectors().
- Added a version of ClassifyLine compiled with SSE (but not SSE2) optimization
for people with Pentium 3/Athlon XPs to use.
- Added ClassifyLine backpatching for the GCC Windows build. The first time a
function calls ClassifyLine, it has to check which version to use and jump
to the appropriate one. After that, it calls the desired one straight away.

ClassifyLine routine or a version compiled with SSE2 optimizations. This
pretty much removes any reason to do a separate SSE2 build, since most of
the time is spent in ClassifyLine, so using SSE2 in just that one function
helps the most.

nodes inserted into it to make a red-black tree worthwhile.
- Added more checks at the start of ClassifyLine so that it has a better chance
of avoiding the more complicated checking, and it seems to have paid off with
a reasonably modest performance boost.

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.

- AddIntersection() should convert to doubles before subtracting the vertex
from the node, not after, to avoid integer overflow. (See cah.wad, MAP12
and MAP13.) A simpler dot product will also suffice for distance calculation.
- Splitters that come too close to a vertex should be avoided. (See cata.wad.)
- Red-Black Tree implementation was broken and colored every node red.
- Moved most of the code for outputting degenerate GL subsectors into another
function.
- Removed forgotten debugging file dump from WriteSSectors2().
- Enabled reference optimization and COMDAT folding in the linker for a slightly
smaller executable.
