Subject: liblbx: Don't scale palette values internally.
X-Git-Url: https://git.draconx.ca/gitweb/liblbx.git/commitdiff_plain/4e74df93acc6594cd8a212c30dc2b429520caef2?hp=4e74df93acc6594cd8a212c30dc2b429520caef2

liblbx: Don't scale palette values internally.

Output the 18-bit palette values unadulterated, leaving it up to the
users to do conversion if necessary.  Push the conversion down into the
consumers (currently PNG output and the GTK GUI) where a 24-bit palette
is required.

While we're at it, adjust the conversion to scale to the full output
range of [0, 255].  This is a slight change to the output, so all the
image hashes need to be adjusted in the regression test.
