I don't know about Motif, but for LessTif a rendition is a fontlistentry,
and a rendertable is a fontlist. Except the render* are more powerful.
Basically that's also what the Motif docs say. They even share the
same resource, but you can specify it both as a fontList and as
a renderTable. Also per Motif's docs.
What I did a year ago or so when I did the Rend* stuff for LessTif
was implementing all this without doing double work. Meaning that
XmRend* stuff is basically present in the 1.2 version of LessTif,
but the API is missing. In the 2.* versions obviously it is more
complete.
The Motif docs have stuff in them that basically say even how
these structures are cached (because they talk about sharing them).
I'm not sure whether I have all that right in LessTif but nobody's
complained yet.
As there is sharing involved, threading might be an issue. Or maybe
that's not what you meant.
Testing. Ah well. I've built a couple of tests that are explicitly
mentioned in the status messages (for this purpose). Also I've been
using Nedit as a testbed, with the X defaults settings that I mailed
about in the last week or so :
dell: {12} head .Xresources
!
! Xft Experiments
!
*renderTable: xft
*xft*renditionForeground: blue
*xft*fontName: verdana
*xft*fontSize: 12
