[GtkGLExt] Request: example of SELECTION and PICKING

[James Don <jimdon sympatico ca>]

Hello,

I am learning opengl ... i have a scene rendered now (which is very
simple) ... it contains cubes etc ...

I am right now trying to implement "picking" (with the mouse obviously)
of objects in my scene ... 

I have found many tutorials using GLUT regarding this ... but none for
gktglext ... is there a chance someone could add an example of picking
to the www page :-)

In the mean time i will keep plugging through the GLUT examples trying
to figure out what i am doing wrong ...

Best regards,
Jim
