As I look at which group I've landed in... newusers it seems.
I understood that, almost. I've only tried a waving flag before using
bicubic_patch and then uv mapping an image onto it, just to see if I could.
The difficulties I see with those is the multiple patches stuff, tying it
all together. Something to try more of someday.
