I've removed the need for the 'count' on the POLY command. The parser
still recognises it, however the interpretor completely ignores any
values passed and simply plots (size of array) / 2 points.
This does mean however that if you create an array size 10, it will
plot a 5 sided polygon. Also, if you only populate 8 of those 10 array
entries, the last two array entries will be zero-filled and hence the
final point of the polygon will be at (0,0).
