Thanx.

While we're on the subject of Performer documentation and Performer
lightpoints... Can anybody explain why it doesn't seem possible to
resize lightpoints beyond about 4 pixels on a RE^2 while pfAntialias is
set to PFAA_ON??? The documentation for Performer lightpoints states
that they can be sized as per the pntsize/pntsizef manpage... this
doesn't seem to be the case. I've got GL code that runs on the same
machine which can size points well beyond 4 pixels. Albeit under
multisampling they are kinda square. (pntsmooth()'ed point are round
however).

Should the documentation for pfAntialias() or pfLPointSize() be updated?
Or am I doing something wrong here?

Or is the behaviour scheduled to change for a future release?

Thanx.
