+### 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

+ # 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

+ # one where they won't load. I'll look at that next, but, for now, this.
