gfx_test: Refactor animation loop and handle hotplug events

This had a little too many indentation levels already. So move
much of the main loop into its own procedure `Run_The_Show()`.

In all inner loops, we regularly check for hotplug events now
(every 500ms). To avoid tracking the time passed even in cases
when we got interrupted by a hotplug event, we switch to a glo-
bal deadline. This also gives us a more predictable runtime.
