P: Save 1:1 Previews from Develop Module

[Winston Caulfield]

When displaying pictures in the Library module Loupe view, there is always a noticeable (2-3 sec) time lag to display a picture in full detail. E.g., at 100% magnification, either by zooming in from "Fit", or when displaying next picture while at 100% magnification, the picture is initially fuzzy and refreshes to sharp detail in about 3 seconds.

Since I always generate 1:1 previews on import, I believe this delay is because edits that I've made in the Develop module have invalidated the previous previews. Typically I will have viewed the picture at 100% magnification in Develop, so a full-size image has been generated by Lightroom.

IDEA:  when changes in the Develop module invalidate the preview, save subsequent views generated in the Develop module as previews. E.g., if the image is displayed at 100% in Develop, save that as the 1:1 preview. This would avoid the several-second delay to generate the 1:1 preview in Loupe view.

I could see a benefit to this. There would be performance implications for a new 1:1 preview being rendered, but the data's already in memory, so it could well be worth a preference setting.
