Hi Paul,
the warnings:
(2) : warning C7531: global type sampler2DRect requires "#extension
GL_ARB_texture_rectangle : enable" before use
is "normal", OSG automatically enables the extension.
The cast warnings can probably be fixed, I did not look at these at the
time.

Is it me or can somebody explain why when I "setenv OSG_NOTIFY_LEVEL debug" and
then run osgstereomatch example and I'm seeing the following all these warnings in the
output (see below). It seems like things are running okay (maybe because these are only
warnings :-). I'm running with OSG 2.6 with the OSG Data Set from OSG 2.6 but I don't
think anything has changed in this area since then... I don't get any messages when I run
without the notify level.
I'm not sure what the intended action is in each of these cases but there seems
to be alot of warnings (in my opinion they should be errors).
