I think it's 'a' through 'm'.

I think one aspect of this description needs updating in light of #238 (as expected) and the second isn't accurate relative to the example. This is will now be following the selection criteria rather than "making choices". And I don't think it's doing any speculative loading -- it's choosing 3 as it should. Or maybe that's what was meant.
I think going forward we can talk about the algorithm now that it's nailed down, and occasionally talk about speculative loading. For the latter I want to get away from the term "preload" because we're using that for adding patches to a file on the server side.

The example shows howed a mixed (table + glyph keyed) IFT font would typically be processed by a client.
