I have written a plug-in which does PTViewer's math in native code.
It takes over the applet's tasks if it is present, while the java
code is executed when the plug-in is absent. This is transparent to
the user.
The speed improvement is not too impressive (~30%) which is due
to the slow interaction of java and native libraries. Maybe I can
speed this up somehow, but it is not worth the hassle of a
plug-in installation in the present state.

PTViewer 1.0 is within 5% of the LP viewer.
There are a few dirty tricks (not in LP!) which I am not going to use like
rendering just a small window and blowing that up etc.
