- pttex.cpp: Bug hunting. if EngineProcTex::Animate(),   changed reference to csSector to iSector. Squashes bug   in bot cam. Changed reference from csMeshFactoryWrapper   to iMeshFactoryWrapper. This squashes a crasher that was   occuring in 16bpp software renderer. Also corrected   reporting about speed of the metaballs, and switched on   the lighting for the metaballs so the texture can be seen.   Note: After a little experimentation, it seems to me the   CS_TEXTURE_PROC_ALONE_HINT flags dont seem to be   necessary. I have not removed them, but if needed, they   could possibly be removed. Further testing on other   platforms would be required.

- ptlab.cfg: Decrease the size of the metaballs and the
  window size. Makes the mwetaballs clearly visible and
  the window decrease is to allow the console messages
  to be seen during initialization (and to be considerate
  to those few individuals that are still on 640x480 res).
  Knocked the iso_level down ( increases size slightly,
  but also gives a more 'blobbier' effect ;), and
  icreased the speed slightly.

- sproctex.cpp (simplept tutorial): Added
  CS_TEXTURE_PROC_ALONE_HINT flag the the
  procedural texture. This stops it from crashing
  in 3d software mode. *WARNING* If this causes
  simplept to crash under other renderers (eg, opengl)
  then please let me know, and I willrevert this patch
  and look closer at the problem. AFAIK the procedural
  texture in this case is truly alone, so the hint is
  probably valid in this instance.
