### Status of qemu images.
# - runqemu qemuppc64 comes up blank. (skip)
# - qemuarmv5 comes up with multiple heads but sending "head" to screendump.
# seems to create a png with a bad header? (skip for now, but come back to fix)
# - qemuriscv32 and qemuloongarch64 doesn't work with testimage apparently? (skip)
# - qemumips64 is missing mouse icon.
# - qemumips takes forever to render and is missing mouse icon.
# - qemuarm and qemuppc are odd as they don't resize so we need to just set width.
# - All images have home and screen flipper icons not always rendered fully at first.
# the sleep seems to help this out some, depending on machine load.

# This is a really horrible way of doing this but I've not found the
# right event to determine "The system is loaded and screen is rendered"
#
# Using dbus-wait for matchbox is the wrong answer because while it
# ensures the system is up, it doesn't mean the screen is rendered.
#
# Checking the qmp socket doesn't work afaik either.
#
# One way to do this is to do compares of known good screendumps until
# we either get expected or close to expected or we time out. Part of the
# issue here with that is that there is a very fine difference in the
# diff between a screendump where the icons haven't loaded yet and
# one where they won't load. I'll look at that next, but, for now, this.
#
# Which is ugly and I hate it but it 'works' for various definitions of
# 'works'.
