Subject: [PATCH spice-common] canvas-base: Fix width computation for palette
images
Palette images are encoded with a slightly larger pixel than
width. This cause a wrong calculation of stride_encoded value
which cause a wrong stride adjustment.
This fix bug https://bugzilla.redhat.com/show_bug.cgi?id=1508847.
