shape-duplicator.jsx

//Shape Duplicator - a tool to duplicate shape layer into another group
//!!!alpha version

//An attempt to create the function which will duplicate a shape group into the selected group
//similar to Ctrl-G command which is missing in ExtendScript
//The main idea is to recursively walk over all the properties and property groups
//of a shape layer and then to create similar objects with similar hierarchy in another group


//Known troubles
//--Stroke dashes and gaps are now not supported
//--Gradients are not copied
//--Keyframe Interpolation visually right, actually wrong
//--Tangents are not supported

//now it's manual
//use rd-GimmePropPath to get these paths

recipient.name = donor.name
