Add "query playground" #406
Conversation
- Adjust the rotation center of the cursor so that its single pixel is gets rendered onto a single stage pixel instead of being split across 2-4 stage pixels. - Add canvas CSS to make most browsers scale the canvases without interpolation.

Maybe this is a weird idea. What if this wasn't drawing but was calling delegate methods. Methods on debugCanvasContext. Then the different playground pages could change what they use about this data if that would be useful.

I like the idea of delegates. That could also solve another problem I've been having, where using "the" debug canvas is basically impossible in some projects since you only get a brief glimpse of the thing you're interested in before the canvas gets overwritten by the next thing. This could be solved by including some basic context info when calling the delegate method so the delegate could decide which data to handle, and how.

I explored this idea a bit and it started getting super complicated, mainly due to the differences between the CPU and GPU paths. It might be better (or at least easier) to have canvas-fetching delegates or something like that... I dunno. Anyway, I still like the idea but I think I'm filing it under "future work"...

Reason for Changes
This should help figure out what's going wrong with
touching color?, as well as making it easier to add more playgrounds in the future if necessary.
