It's nearly finished as far as I can tell, still missing some 3D box icons but I don't know what they should look like.
Major changes since last version: *all icons are done *changed look of raise/lower icons *"tweak" tool uses "smudge" icon from art libre set *transform icons taken from art libre set *align icons taken from art libre set (or extrapolated from their style)
problems: ink pressure/tilt settings don't show (but the old ones do for some reason) some icons are taken from the desktop's icon theme and so the layer icons should match the ones in the layer dialog but don't match on all platforms same goes for paste icons like paste in place that don't always match the look of the generic paste icon.
