System: NetBSD 9.99.108 NetBSD 9.99.108 (POWERMAC_G5.MP) #75: Fri Dec 2 14:06:11 CET 2022 macppc
Architecture: powerpc
Machine: macppc

The latest pixman update breaks display of sized images on (at least)
macppc. I have a system with firefox52 from pkgsrc, nothing else
changed and all working fine. After upgrading base (including X) form
Sep 20 to todays current sized images display with wrong colours in
firefox. This includes the tab title display of most favicons, but also
other images on web pages that are scaled.

Downgrading pixman to 2.2 fixes all issues.

Fixed by r1.2 of xsrc/external/mit/pixman/dist/pixman/pixman-fast-path.c,
awaiting upstream resolution:
Undo upstream commit b4a105d77232a87304b7b621e2f99e699a8eebd3, it breaks
colours on big endian machines. Also reported upstream.
