Default Reducing shimmering

Shimmering is often times a big problem in panos, since the images are moving and zoom levels change etc.

This can be reduced significantly by applying the "power of two" to the images used.

Cubefaces should only be any of the following sizes:

512x512
1024x1024
2048x2048
4096x4096
8192x8192

Please note that the bottom two sizes are not going to work in the current version of FPP.... but that is going to change.

Other graphics (hotspots) should be using sizes based on the same "power of two" concept:

2
4
8
16
32
64
128
256
512
1024
etc.

So a hotspot could be 64x128 or 32x256 or any other combination of the above numbers.

This will not REMOVE the shimmering, but it does absolutely reduce it, and make things look better.

Here you can see a test, where the upper image is sized according to the above "power of two" principle, and the lower image is not:

Make your own tests to confirm this.
