The JoglConeRendering sample program works perfectly for me on Linux, on
the Mac the window opens but is blank. After a few seconds it exits with
this output:
We are using com.jogamp.opengl.awt.GLCanvas for the rendering.
Assertion failed: ("pre: is_bound" && this->IsBound()), function
SendParameters, file
