Status update:

Copying everything but the front-end code from the Unix source package  
worked just fine. I now have a version of POV-Ray that can both read and  
write HDRI data in OpenEXR format, and which outputs an unclipped image  
when a HDRI output format is chosen.


I now have a few questions for the POV community:

- Is support for 32-bits per component floating point output desired?
It wouldn't take much effort to do, but I doubt it's needed/useful.

- Is support for the Radiance HDR format desired?
It's a trivial thing to add, so unless the answer is a resounding no, it  
will most likely be done.

- What kind of functionality is desired regarding exposure control, and  
how would you like to see it done?
I have a few vague ideas, but I have yet to investigate their feasibility.

- What kind of support applications are desired?
Currently I have only a small program that can convert between OpenEXR and  
Radiance HDR, but I'm considering doing something a little bigger that  
would let you do some limited processing (e.g. exposure control,  
downsampling) on OpenEXR images.
