+//
+//                 PC_relative - texture pathnames are made relative
+//                 to the indicated tpc_directory.
+//
+//                 PC_absolute - textures are looked up along the
+//                 search path and then converted to absolute
+//                 filenames.  tpc_directory is ignored.
+//
+//                 PC_rel_abs - as above, but the resulting filename
+//                 is guaranteed to be relative to tpc_directory, and
+//                 may include a number of ../ paths to guarantee
+//                 this, if necessary.
+//
+//                 PC_strip - pathname components are stripped from
+//                 the texture names, and only the base filename is
+//                 retained.
+//
+//                 PC_unchanged - texture pathnames are left exactly
