I am not talking about OpenEXR support (to me being required to download 
9MB to add support for a new file format is quite out of question).  I 
am talking about plain binary floating point data.  I stopped studying 
your code snippet when i read:

typedef unsigned long uint32;

POV-Ray should compile on any platform where a C++ compiler is available 
that supports the current standards.  So for writing portable extensions 
for POV-Ray you should comply with the standard first of all (and if you 
do it will most likely also compile and run on most platforms.

And the typedef cited above is a serious affront to the standard...
