- The Graduated Filter on-canvas widget button now has its own icon,
does not use the curve's "add adjustment point" icon anymore.
- When dragging a crop, a closed hand cursor is shown.
- The hand icon had the outline removed to improve separation between
the fingers.
- The mouse cursor now is an open hand when hovering over something
which can be panned, e.g. the red square in the Navigator panel. It is
a crosshair when hovering over the main preview.
- When you pan the red square or the main preview, it's a closed hand.
- Now the cursor changes to a crop icon when you're in crop mode.
- The cursor changes as needed when you want to resize a crop edge or
corner.
- The cursor changes when you're in straighten mode.
- The curve "add adjustment point" and "edit node in/out values" icons
now contain a node in the icon and are more representative of what
they do.
- The small reset/undo icon is made a bit clearer.
- 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.
- Perspective, distortion and crop icons redesigned.
- Some small icons were missing the `-small` suffix, now renamed.
