Re: Canvas Floating Point Color Values Propoal

Needs statements about conversion between unorm8 and float16 representations.

I assume such conversions will be needed.

 

Also, spell out that the float16 encoding is as per IEEE?

As discussed in the previous call, I've separated floating point pixel values from HDR canvas capabilities. 

 

The following document is that proposal.

Please provide any feedback you have on the proposal. I will be trying to get this landed in the HTML spec first, and then introduce the HDR canvas proposal separately.
