+Subject: [PATCH] fix colors on big endian systems
+
+with gtk3, cairo is used, which has a different representation for
+their RGB24 format in memory depending on endianness. Since bit
+shifts abstract away endianness and work on arithmetic basis, having
+separate code for big and little endian has incorrect results.
