Files for testing JPEG XL colour profile support:
* correct.jpg → Photo of a Panther Chameleon in sRGB colour space.
* in-srgb.jxl → The same photo in JPEG XL format.  Should render the same as
                correct.jpg.
* in-p3.jxl   → The same photo in Display P3 colour space with embedded colour
                profile.  Should render the same as correct.jpg.
* wrong.jpg   → The same photo encoded in Display P3 colour space but with the
                colour profile stripped.  Represents incorrect rendering result.
                If JPEG XL decoder does not support embedded colour profile,
                in-p3.jxl will look like this image.

# Creation

The files were created as follows:
* correct.jpg → Original file downloaded from Wikimedia Commons.
* in-srgb.jxl → The above converted to JPEG JXL using `cjxl -j 1 -e 10
                correct.jpg in-srgb.jxl` command.
* in-p3.jxl   → Original file first converted to Display P3 colour space using
                GIMP and then converted to JPEG XL using cjxl.
* wrong.jpg   → Original file first converted to Display P3 colour space using
                GIMP and then having its colour space stripped using
                `jpegtran -copy none -optimize -progressive in-p3.jpg
                >wrong.jpg` command.
