You can't check GPU support from within a plugin as a plugin doesn't
neccesarily have a valid graphics context - rather its later code that
should check this.

I'm not the author of the HDR plugin so know little specifically about
the HDR plugin. Is there are legitimate versions of the HDR format
that are presently supported that should be the please add this
support and submit it for inclusion in the SVN version of the OSG,
this way it'll be in the next release.
