Attrib("paste:p14" "grid,5,4,50%,470pL")

Means: paste for pad p14 is a 5x4 grid, 50% coverage, total of 470pL ?
I suppose glue:p14 and other attributes would work too.

Hmmm... drawing hooks.  "I know how to draw XYZ" could match up with
Attrib("plugin:foo:..." "...")

I suspect designing an API to handle different plugins handling
different aspects of each footprint, and priorities, would be tricky.
