Release roadmap:
1) {copy,cut,delete,insert from,paste}, edit asset in new canvas, import from {canvas,object}
2) floating/dockable toolbar https://wxpython.org/Phoenix/docs/html/wx.aui.AuiManager.html
3) allow dragging {circle,rect,...} w/ <Ctrl> irrespective of current brush size
4) reimplement cursor unmasking w/ simple list of points
5) operators: crop, scale, shift, slice
6) auto{load,save} & {backup,restore}
7) tools: unicode block elements
