OK, sorry. Now I compared glean/pixelFormats, and this
extension doesn't make any difference at my place.
Neither any fix nor any regression.
Which probably doesn't mean a lot, because there's a
significant number of piglit failures either way. 

I found another test that appears to use
ARB_half_float_pixel, fbo/fbo-rg, but it gets skipped
for lack of GL_ARB_texture_rg.

Sounds interesting. For the moment, I guess I'll prepare to
file a couple of bugs for problems I found.
