icon-view: Display hidden files with transparency

[vkareh]

Render hidden files with some transparency to visually distinguish them from regular files. Files become fully opaque when selected or highlighted.

Fixes #1872

I couldn't test yet, but looks fairly reasonable.

This said, shouldn't the text also be dimmed? Especially in list/tree mode, having only the icon dimmed might not make so much of a difference, does it?

Good question, but I'm not sure about that. The icon is a quick visual cue, whereas the text is meant to be read. Making it less opaque will affect contrast and therefore readability and accessibility. For comparison, nautilus doesn't seem to dim the text either.

I think I am doing something wrong, for me I can not see any transparency.

Because caja is running your desktop session directly, you might need to do something like:

$ killall caja
$ caja --no-desktop
