sRGB v2 profile

An ICC v2 sRGB profile is provided below, with XYZ black point scaling to zero. This profile has the preferred rendering intent in the header set to 'perceptual'.

The profile contains the standard linearized Bradford D65 to D50 chromatic adaptation tag (this tag was often not present in older sRGB profiles), and the media white point tag is set to D50 (as is required for ICC v4 display profiles and recommended for v2 profiles). This avoids the inappropriate color casts that older sRGB v2 ICC profiles sometimes produced when the absolute colorimetric intent was used.
