selected, and sprites don't get picked through portals. As a rule of thumb,
don't be too far away from the objects you're modifying in 3D mode.

has the same resolution as getticks (1000 Hz). For Windows and SDL 1.3,
the resolution of the underlying perf-timers is used. The only user of
these functions right now is some TROR on-screen debugging code.

functionality, Polymost).
The new feature can be enabled/disabled with the 'r_tror_nomaskpass' cvar.
The basic idea is that when drawing lower or upper levels, a first pass
is performed that ignores all red walls for which the TROR nextwall link
'towards' the viewer arrives at a red wall. Thus, in the worst case, there
can be up to twice as many rendering passes now (when it is discovered that
the no-mask-pass isn't different that what would be drawn with the ordinary
one, the latter is skipped, since we've already drawn all needed geometry).
Hovever, this kind of multi-pass splitting is only suitable for simple scenes,
like the upper subway in the TROR test map. In particular, multiple islands
shouldn't 'see' each other.
Two issues are worth mentioning: first, care needs to be taken for translucent
ceilings or floors, since drawing them twice isn't the same as drawing them
once. This is done for classic, but not for Polymost. Second, sprites (which
are always drawn _after_ the geometry for a given pass) are still clipped to
the geometry of the ordinary pass, resulting in their disappearance from
certain angles.

Additionaly, a change made it into this commit that fixes redundant collection
of sprites in TROR:classic/Polymost.

With script_expertmode enabled, SHIFT-BACKSPACE clears the upwall link and CTRL-
BACKSPACE the downwall link. These functions are useful because the automatic
nextwall determination code sometimes gets it wrong (not corrupting anything) or
if you want to vertically displace a sector attached to a higher or lower level.
Also add the exploding ceiling example to the TROR test map.

In cases where performing occlusion queries for multiple red walls
leading to the same sector, we would sometimes leak a number of
query objects. This was apparently harmless on NVIDIA drivers, but
would leak tons of memory on ATI.

The code was using the Polymer-cached version of the sector cstat to
determine the translucency of its diffuse material, meaning it would
never get it right on the first try; that's what you get for having
completely different variables named 's' and 'sec'.
