“Fà e desfà l’è töt un laurà”
“Do and undo are both a job”
(A proverb from Brescia, Italy)
In order not to load all the images of a directory and hence saturate RAM, only the surrounding images of the current one are loaded. This has been implemented in r74, obtainable via Bazaar (see “Get it” page for details).
So while you step to the next images, luce loads one image which is ten images forward and unloads an image which is eleven images backward. Well, kind of.
This makes luce baaarely usable, and still very fast.
