Linearize an sRGB-encoded float texture in place, leaving alpha alone.
Alpha is coverage, not colour: it is never gamma-encoded, and running it
through the EOTF would make every partially transparent texel more transparent
than authored. The same exclusion the writer applies when it computes
texture_data_range over RGB only.
