[GEM-dev] bug: geos vertices messup with draw full/fill message

[B. Bogart]

Thanks for reporting this Erich!

I was about to revisit the issue, but I've not yet converted my old geo
switching patches to pixelTANGO.

Also I'm working on a abstraction geo called supercube that you may
like, I'm sure we'll have a chance to geek out a bit in Helskinki!

Glad you beat me to it.

I can confirm this error (on OSX)

Oh and also the error is NOT dependant on the alpha, that just makes the
error visible. I've included an alteration of the patch with lighting
and no alpha and we can better see how the vertecies are drawn. I'm
pretty sure draw fill is drawing the vertecies with some points
reversed. I only had this error when I started dyanmic patching, so I
thought that was the cause, not the draw fill part, which was also in
that patch!

pt.light is included just to save me time.
