"With HSV, if you mix red and blue, you obtain cyan and not white."
Huh? How do you get white from red and blue? For that matter, shouldn't 
you get magenta and not cyan (blend hue by nearest)?

I just fought with trying to blend colors in HSL, and it's really hard 
because of the discontinuity (which is why I ultimately gave up and went 
to RGB). The only "right" way I could figure out to blend hue is to also 
affect chroma at the same time, i.e. arrange so that exact opposite hues 
result in zero chroma.

"Docker: out ! Validates what on the wiki."
What does this mean?

"Add an age field to the tiles instead of a list of tiles that can be 
swapped. That way for each access the tile is time stamped, and then 
background thread swap the oldest tile."
Has using a queue of most/least recently touched tiles been considered 
(move tile to head when you touch it)? Or do you do both?
