minor video bug in deus ex machina demo

[tfisher]

In the crest/oxyron demo "deus ex machina", there is a minor display glitch visable in the coke can display part about 3/4 of the way through the demo. In the lower right hand corner of the screen (in lower border area) there should be a logo of a pair of legs running. In CCS64 v3 beta 1.5, only one of the two legs shows. This is some kind of sprite bug, maybe a priority issue(?). This displays correctly in VICE 1.15, for comparison.
