...ok, after playing around with this even more, I noticed that it's 
not a problem with area averaging, but with how the "dots" actually get 
drawn...it became apparent when I was looking at some of the other 
shapes (diamond especially):  the left side is being drawn correctly in 
yuv, but not the right side...this must have something to do with the 
calcCorners or the rotate vertex algorithm, but I haven't picked it 
totally yet...

...just some public musings...
