Snippet with shear transform

I'm encountered a problem where code that uses shear transform suddenly looks "wrong" compared between windows+linux.

The root cause is that it seems that under GTK the shearX+shearY values are exchanged.

I have attached a snippet and demonstrates the problem.

Can you please try https://git.eclipse.org/r/c/platform/eclipse.platform.swt/+/176681 ? It's supposed to fix this one.

How can I apply the path? Do I need to compile the native code?

There is https://wiki.eclipse.org/SWT/Devel/Gtk/Dev_guide#Rebuilding_gtk_.2A.so_binaries about recompiling the natives but patch has been merged (thanks for the urge) so you can just wait for tomorrow build.
