1371          thf2rad - convert GDS "things file" to Radiance scene format
1372   If anyone is still wanting any of the above programs, let us know and we'll
1373   reinstate it.
1374 +
1375 + Fixed bug in pcond's acuity simulation for small view angles (less than
1376 + 4 degrees horizontally or vertically).  Thanks to James Lee for figuring
1377 + this out.
1378 +
1379 + Added script to convert to/from ICT's Poskanzer Float Map, which I don't
1380 + care to support officially due to its machine-dependent byte order.
1381 +
1382 + Fixed bug that caused incorrect reporting of non-surface in set when
1383 + mixing meshes and instances.  (Thanks to Jack de Valpine for discovery.)
1384 +
1385 + Fixed innacuracy in calculation of diffuse transmission in the presence
1386 + of pure specular (Fresnel reflection) using "trans" material.  Thanks
1387 + to Christoph Reinhart for pointing out the error.
1388 +
1389 + Made internal change to tone-mapping library to use structure pointer
1390 + rather than stack, making code re-entrant and more up to modern standards.
1391 +
1392 + Added -pd option to handle depth-of-field blur in rpict.  This requires
1393 + that the view directon (-vd option) include focal distance information,
1394 + which is now preserved by the various view file routines, and reported
1395 + by the vwright command.
1396 +
1397 + Added DBLUR variable to ranimate and pmdblur script to handle simultaneous
1398 + motion and depth-of-field blurring.  Thanks to Visarc for funding this work.
1399 +
1400 + Added setting of focus distance in rvu ("focus" command) and rholo
1401 + ('f'/"frame" command).
1402 +
1403 + Changed default remote shell in ranimate to "ssh" rather than "rsh",
1404 + which has been abandoned on most Unix systems due to security issues.
1405 +
1406 + Fixed behavior of source primitive using illum with no alternate
1407 + material.  These now become transparent so one can see the sky or
1408 + light-probe background for use in image-based lighting.  Previously,
1409 + the user needed to specify the background glow as the alternate
1410 + material for a distant illum source to behave properly.  (This still
1411 + works.)
1412 +
1413 + Fixed some minor problems and inconsistencies with 16-bit/channel
1414 + TIFF i/o in ra_tiff.
1415 +
1416 + Created mksource program to generate distant sources for improved
1417 + image-based lighting with light probes.
1418 +
1419 + Changed ambient calculation so that -ad will not limit recursion
1420 + depth, and a minimum of 27 samples will be sent out for each stored
1421 + ambient value, or 3 samples if -aa is 0 (caching off).
1422 +
1423 + Added -oM option to rtrace to report material (rather than modifier)
1424 + for cases where actual material is aliased or further up modifier chain.
