16 bit images should auto scale on load

Description (last modified by afraser) (diff)

16 bit images should use "pretty good" auto-scaling by default. (5%-95% or whatever IJ1 does)

EDIT: IJ1 does something different.

Test on the CT sample image which renders very differently in IJ1 and IJ2

Need to fix #795 first

Duplicated this bug with the latest code, using T1 Head. First save to TIFF, then reopen in ImageJ2, and the range is set to 0-885 instead of 3-521 like ImageJ1 does. As stated above, the reason is that ImageJ1's default autoscaling is not a naive min-to-max but rather a statistical range computation.

This ticket does not fit the beta4 theme of plugin work. It will fit in marginally better with the beta5 theme of flexible data handling.

Fixing this requires image statistics and histogram info. Wait on ticket #1384

In general the default autoscaling method should be modified to do what IJ1 does. And it should apply to all kinds of images and not just 16-bit.
