Bug Description

Marlin shouldn't scale up images for image previews. This causes images to appear pixelated.

We should generate larger tumbnails for the context pane, 256*256 would be nice.

Hmm, that's exactly the opposite behavior as described in the report. If an image is only 24x24px and you scale it up to 256x256px it's going to look really really really bad. If an image is 24x24px it should remain 24x24px.

Ok, I meant that we should just generate larger thumbnails for the context
pane, to avoid scaling up them.

Hmm maybe a picture will help explain. This image is 34x34px. Marlin scales it up to 48x48px and it becomes blurry and pixelated. Now, imagine that scaled up to 256x256px. It would be awful. We should never force an image to display larger than it actually is.

Oh ok, I didn't understand, I tought you talked about the context pane
(but there is a problem there too).

So, what xapantu means is this other bug?
