Added feature to merge a layer with the layer below
Done at #jsconfeu2014 :)
New icon in icons : merge-icon.png
TODO : reorder the icons folder, it's waaaaaaay too messy !!
Added 2 new icons :
- Animated Preview Panel : toggle onion skin
- Layers Toolbox : toggle layer preview
Added an icon font generated with icomoon.
SVGs for both icons have been made under Inkscape and are kept under
misc/svg.
All reference SVGs have been moved to misc/svg.
Added 2 keyboard shortcuts for toggling onion skin / layer preview :
- alt L : toggle layer preview
- alt O : toggle onion skin
- added rename icon in layers list
- mutualized CSS for edit icon between palette manager and layers list
- new CSS file icons.css for actions/links/buttons using icons
- layers are no longer retrieved by name, but by index
