The star icons used for ranking thumbnails are now of the "narrow" size,
i.e. 10x16px. This change removes mostly the padding, which caused the
ranking buttons to bloat the minimum thumbnail size to an unacceptably
large size.
- Color-unranked icons tweaked for lighter themes, closes#4704

- Tweaked window-add, used for adding detail windows.
- The "light" icon theme is now a little lighter, to increase contrast.
- Toolbox icons are now small.
- Buttons:
- Buttons without labels which use icons as their only source of info regarding what the button does (e.g. the white-balance pipette button) use normal-sized icons.
- Labeled buttons which use icons as an auxiliary source of information (e.g. Auto-Crop) now use small icons. Curve type icons are also small even though they have no labels.
- Colored circles are smaller.
- Curve type icons redesigned and small.
- Hand icons (when panning the preview) redesigned to have a clear outline regardless of background color.
- Magnifier icons redesigned to have a thinner magnifier frame and larger inner parts.
