Mouse buttons are mapped incorrectly on prism. Clicking the middle mouse button is reported as 'secondary' button and clicking on right button is reported as 'middle' button.

To reproduce the bug, run the attached test and try clicking button 1,2,3 within the red rectangle. For correct behavior, you can compare with swing pipeline.

I reproduced on WinXP - Soma-graphics-scrum-b142-6u14. Not reproducible with swing pipeline.
