 bytes on standard input.

+Created rcode_depth tool to convert to and from a 16-bit/pixel portable
+depth image encoding that uses a mix of linear and reciprocal distance
+with explicit representations of 0 and infinity.  Code for loading these
+depth maps is in src/util/depthcodec.{h,c}.
+
+Created rcode_norm tool to convert to and from 32-bit/pixel portable
+surface normal representation, matching the one in src/common/dircode.c.
+Code for loading normal maps is in src/util/normcodec.{h,c}.

+Created rcode_ident tool to create indexed identifier files.
+Code for loading these files is in src/util/idmap.{h,c}.
+
+Added -o* option to rtpict to produce layered images that handle most
+output types from rtrace (colors, surface normals, distances, IDs).
+
+Created rcode2bmp script to create images from new rcode_* output maps.
+
+Improved efficiency of rmtxop in cases where matrix multiplication is
+faster evaluated right-to-left, as when the final component is a
+column vector.
