I think I like the uniform "hb-*" more.

More useful.

Add a non-hooked _png _svg get emoji blob

Yep, was not recognized without this patch!

This is like hb_script_t.

We had this exposed as unsigned int since 2.0.0 release in two APIs,
as well as hb_ot_layout_get_size_params() from earlier.
But since no one uses those (right?!), let's just fix this now.

Don't know how to document anonymous enum members.

And swap return value positions, so can be annotated for gobject-introspectin.
