We still end up short if we just discard these counts - still don't
need faces for them, but every edge could be real unless it's shared
with another skip face.

The old assumption about unique verticies is sometimes untrue when
skip faces are included in the map. Be more generous with the vertex
memory allocation. This is not an area of peak memory usage anyway, so
shouldn't be a big deal.

Extend skip support to recognise the liquid skip texturenames the same as
metlslime's "newskip" utility. Add documentation and describe hint
surfaces (briefly) as well.

The old logic did not deal properly with the case where the source entity
did not add any brushes.
Signed-off-by: Kevin Shanahan <kmshanah@disenchant.net>
Normally the engine won't do collision detection against a bmodel
unless the entity being tested is within the model's bounds. This
means collision doesn't work as expected when a model has clip brushes
that extend beyond the bounds of any visible brushes. This fixes that
case.

New version returns the list of copied faces. This was the last user of
the inside and outside globals outside of CSGFaces, so they now move onto
the local stack there.

The list onto which to save the faces is now passed in instead of
implicitly using the global outside list.

Only used in two places and not a whole lot of calls, so just allocate the
map while it's needed and free it afterwards. There is no relationship
between the two users, so no need to share a common block of memory.

We pass in the face list and the plane map to link the faces to. Update
the comments to make it clearer what the function actually does.

At load time we defaulted to CONTENTS_EMPTY, but if part or all of the
brush lies underwater, then inherit the water contents type.

Check that the hint face would actually get split before we discount the
candidate split plane...

Similar to the skip texture handling, add miptex flags, handle
appropriately in CSGFaces and SolidBSP, then remove the surfaces before
writing out the bsp.
Lightly tested, but seems to do all the right things.

FreeInside was a strange name, since depending on the arguments we
actually wanted to keep the faces.

Now consolidate the leak state into a single leakstate_t struct. Rename
the leaks/numleaks/maxleaks members as portals/numportals/maxportals for
improved clarity. What was numportals previously is now numwritten.
Outleafs is now returned from the FillOutside_r function instead of
passing in a struct or int to be incremented by the function.

Finding leaks carries a lot more state which is not needed for the final
outside fill stage, so let's separate the two. Get rid of fillparms_t
since the only thing left was the fillmark.

It seems clearer now that the numportals parameter is actually used to
check that the number of leak portals we accumulate doesn't exceed the
allocated memory. Update the structs to reflect that.

Move the 'firstone' global into the bspleak state as a flag to indicate
whether the header has been written yet, since that's why the flag exists.
Move numportals and hit_occupied (renamed to "entity") in there as well to
keep leak related data all together.
MarkLeakTrail now directly increments bspleak->numportals so doesn't need
to return a value indicating what was written.

Was showing up as blah.prt.por because we had messed with the filename to
remove the prt file previously.
Signed-off-by: Kevin Shanahan <kmshanah@disenchant.net>
Previously, leak files would only be written for a leak in hull 2. This is
actually pretty bad because a small leak in hull 0 or 1 might not show up
in hull 2 and you would never get a leak file to chase it down.
Place a flag in the global mapdata to indicate whether we have written a
leak file or not so we only write for the first hull that leaks. Hullnum
is no longer needed as a parameter to RecursiveFillOutside, so remove
that from the fillparms struct.

Remove the (file) global fillmark from outside.c and place into the global
mapadata. Pass the fillmark into RecursiveFillOutside as a read-only
parameter instead.
