[Drawkit] warped/warpable grid?

[James Maxwell]

Actually, I just realized that I'd also be talking about a grid which  
is asymmetric along the x and y axes, which is probably kind of  
unusual... It seems pretty clear that I'll need to make a fairly  
complex subclass of DKGridLayer, if I want to take this route, but any  
thoughts would still be appreciated. I'm thinking particularly of  
whether this might be something worth including in the framework, in  
general, Graham(??).

cheers,

J.
