Maybe rather than calling this an IDL2PathMap, we should just call it a
HeaderMap.  It's not really specific to IDLs.

[Daniel Bratell, 2013/04/25 21:24:26]

It kind of is. The binding scripts work on IDL interface names and this map says
where the corresponding header file to include is. It's not a list of all header
files.

It would be possible to have a full header map too, and I had such a thing in
one of the other scripts I used to convert all the source, but since this needs
to be kept up to date with every change, I think it's best for build performance
and for dependency tracking that it's restricted to IDL interface names.

Also, there are (or were?) headers with the same name in the WebKit tree. If
that is the case, or becomes the case, a full header map would become non
deterministic.
