 Checked in cross-platform cmake build system created by Bill Hoffman

+
+=====================
+Version 4.2
+
+Axel Jacobs added -cp and -palettes options to falsecolor.
+
+Fixed bug in matrix output of genBSDF introduced shortly before 4.1 release.
+
+Made rvu more responsive in multi-processing mode when changing parameters.
+Explicit "new" command not needed to show changes, because it goes back
+to "immediate mode" once something is changed.  Processing will be slow
+but response time quick until next "new" command.
+
+Fixed major bug in transmitting proxy material sampling.
+
+Patched cmake build tools (changes by Zack Galbreath).
+
+Removed requirement for pflip -h to be given input file (can pipe from stdin).
+
+Added "Number of processes" slider to trad "Action" pane to control rad -N
+option for rvu and batch rendering.
+
+Added -c option to vwrays to repeat pixels for rtcontrib.
+
+Reworked rtcontrib program and renamed to rcontrib.  New version runs much
+faster, especially on multiprocessor systems, and doesn't require as much
+memory.  No longer calls rtrace; instead does all the work itself.
+
+Added -d option to genskyvec to produce direct-only (sun no sky) vector.
+
+Added Ashikhmin-Shirley anisotropic BRDF model (ashik2) with help
+from Nicolas Boneel.
+
+Added Ruby rewrite of objview.csh by Rob Guglielmetti.
+
+Fixed bug in reciprocity for tensor tree BTDF representations.  Thanks
+to Andy McNeil for identifying the problem.
+
+Added MNAME and ZNAME variables to ranimove for debugging & testing.
+
+Created pmblur2 command to take motion and depth buffers from ranimove
+to compute a better motion blur.
+
+****** COMPATIBILITY CHANGE ********
+Changed BSDF routines to use updated/corrected XML specification and
+removed depracated BSDF support from mkillum.
+
+Fixed behavior of i/o flushing in rcontrib with -c > 1 (averaging).  Thanks
+to Lars Grobe for help identifying this problem.
+
+Fixed bug in depth-of-field blur where view distance was measured from
+fore clipping plane rather than viewpoint.  Thanks to Peter A-B for
+pointing this out.
+
+Added options to dctimestep to allow multiple time steps (-n)
+and multiple output pictures or sensor files (-o).  Also added -i
+option to specify float (-if) or double (-id) input for sky matrix.
