Without this, my mac powerbooks cant use P2D or P3D. I applied this patch and magically solved the issue without noticeable side effects.

Fwiw, here's a writeup of how I did that

I am happy to know that it helped @commonpike . Thank you for sharing!
Please let me know if you notice anything wrong while using it.
I upvoted your solution in SO.

We can't make use of sun.java2d.* classes because they're non-standard. If this is the only way to do it, these methods would need to be called via reflection, so that it can degrade gracefully if the sun.java2d package (or a specific class) is not available.

@benfry understood. Thank you for your feedback!
I don't know yet a different way of doing this.
ce575e9 now uses reflection to handle sun.java2d.*.
Please, let me know if you think it can degrade gracefully enough this way.
Also, I'm available for hire. Is there any interest?

Thanks for the fix, really appreciate it. I've incorporated a version of it over here: processing/processing4@269f626 for Processing 4.x.

@codeanticode will want to fix it up later since there's already FBO enabled/disabled code in there, but at least we have the workaround for now.

@benfry nice!
@commonpike do you mind to test with the latest changes? (ce575e9)
