gotten lost during recent CSS changes. Vlad, could we add that back?
(Or did I miss it during the initial commit?)
It's not completely trivial and would double the number of code paths

in some areas. Also, until browsers have built-in support for high
dynamic range image formats, these conversions will just waste space.
What image formats are supported by browsers are not defined. Any browser can add any formats it likes.
For these reasons I think this should be left to a future revision of
That seems like a mistake to me. Put it now and things should just work. It would suck if some browser decided to add support for some HDR image format but the WebGL spec requires that it NOT work.
