Great, can you please point me to the code in your repo showing the change?
I am curious what the issue was.

The patch is under review @ https://codereview.scilab.org/#/c/20998/

It is not an optimal patch but does the job. The problem is that autoDrawable only has getSurfaceWidth() and getSurfaceHeight() (at least since 2.3.x, here I have tested with master/2.4.0). Depending on the hardware, it can be a GLJCanvas or a GLJPanel, but under Mac OSX I know that it is always a GLJPanel, which explains the brute force cast. If you have a better idea I am greatly interested.
