Is anyone working on (either in POV-Ray or MegaPOV) OpenEXR output? If
not, I've worked out a simple standalone OpenEXR RGB file generator that
doesn't require the ILM libs.

OpenEXR support has been (partly) implemented in the current 3.7 beta.
There are no plans currently to independently add it to MegaPOV.

Does "partly" here mean "reading supported, writing not yet"?

No, partly means the possibilities of the OpenEXR format are only used
to a very limited extent.

We use default RGBA with zlib (ZIP) compression for output, with everything
else using defaults. There are many more options one could use, if one
really wanted to, but which may or may not eb useful to only a handful of
users. For a good overview, check out:

Cool. Is IlmImf lib statically linked? Just noticed povwin.exe is twice
as large than in 3.5.
The half module also uses a 256K lookup table to store half-to-float
conversions... not sure how much that would impact CPU's data cache
during rendering (if POV is outputting to the format as it renders), but
if it does it's easy to override the behavior to not use the table.
