I find the slide rule easier to use with standard zooming as opposed to being limited to (2) fixed zoom values. Someone once said to me "whenever software does something for you it does something to you".

Dear Sir, Thanks

I still have (2) issues with this scene:
1. The slider is not the same scale as the fixed portion. The slider textureMatrix should be [0.006571155, 0.0, 0.5, 0.0, 0.1431, 0.5, 0.0, 0.0, 1.0]
2. I can't pan up and down when running the scene.

P.S. I see part of the problem is that the original image has some distortion.

Looking good.

I made a response scene to this scene. If you don't like me messing with your scene, then let me know and I will remove the response scene.

Good Sir, You are most welcome to improve and add value.... Thanks
