[Sidefx-houdini-list] Film at 16 bit

I forgot to mention that only two image formats supported by Houdini 
support 16b FP - OpenEXR and Houdini .pic. Both also support 32b FP, so 
in order to save them as 16b FP disk images after compositing at 32b FP, 
you'll have to put a Convert COP before the Composite ROP to downsample 
the data to 16b FP. Otherwise it'll save them as 32b FP disk images.

In Houdini 8.2 with OpenEXR this isn't an issue because 8.2's OpenEXR 
implementation only supports 16b FP.

Cheers,
M.
