1:1 preview

[hellpe]

Would it be interesting to allow some way to see how the dithered image looks like in its actual size (apart for the solution proposed in #10?) I can think of two ways of implementing it:

• when hovering the preview, display a square over the mouse cursor with the 1:1 preview
• adding zoom controls to the preview (+/- buttons, mousewheel, etc.)

Maybe I could implement a "mini image viewer" page that would behave mostly like Loupe and would look similar to how 1:1 preview looks in Flathub, but the issue here would be to implement interpolation to that viewer.

Gtk.Picture, the widget used to display images doesn't support it, and without it, images look weird when zoomed out (some weird halftone-like artifacts can show up on display).

This is something to consider implementing, but for now I think I would go with proposal from #10, as implementing such page would take some time and expertise which I don't currently have.
