Support for drawing 'island sectors' for TROR/classic (and with limited
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.

Support for drawing 'island sectors' for TROR/classic (and with limited
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.
