Edit imported Icon Composer bundles with the full vector toolset

Icon Composer .icon bundles used to open in a dedicated Composer mode with its own stripped-down canvas and tools. Now import builds ordinary editor layers and folders, so every path tool, material, and effect works on the imported artwork just like anything else you draw. Group-level glass (shadow, translucency, specular, blur, lighting) from the bundle now carries over onto the corresponding folder’s settings, and undo/redo runs through the normal editor history.

Export keeps every field the app doesn’t model yet by starting from the original bundle and only overwriting what you actually changed, so re-exporting an untouched import reproduces the source file exactly.
