Lifetime Display

[grislis]

Extract a common lifetime display plugin from SP.

The default display of a X x Y x Lifetime image shows a 2D X x Y image with a Lifetime channel slider. This is not useful for anything.

We could handle images that have a lifetime dimension differently. The default display would lose the lifetime dimension and just show a grayscale image with all of the decay photon counts summed.

Clicking on the display could bring up a decay graph by default.

This ticket describes a specific lifetime display capability and not a generic 'display plugin' concept such as was floated earlier.

Having an internal X x Y x LT Dataset and an external, displayed X x Y Dataset is liable to lead to problems. In some cases we would want to access the displayed Dataset, i.e. to set brightness/contrast on this grayscale image; in other cases we want to access the internal Dataset, i.e. to crop the image.

This lifetime display presenting a clickable grayscale representation would be used by SLIM Plugin and potentially by other lifetime plugins.
