I'm not speaking about Debian programs, but third party, like games
from LOKI, or LGP, or some others.

A quick strings | grep libGL over Descent3 from loki showed me:
/usr/local/games/Descent3] strings * | grep libGL
/usr/lib/libGL.so
Specify path to libGL.so:
libGL.so
libGL.so.1
libGL.so.1
libGL.so
libGL.so.1
      working. Use the same libGL.so that you'd use for Quake 3. Glide also
     library. The default is libGL.so (or libGlide2x.so) from your library
  - If the default libGL or user-specified libGL fails to load, 1.4.0a will
    try libGL.so.1 as a last resort...

which might indicate that they are actually opening libGL.so, and only if
that is not there libGL.so.1.

Didn't check the others I have installed.

Yump, but it is reality.
