Find tracks, exposed parameters, links and more of parameters
The sourceElements() function return the elements that have pointers to this Object: tracks, exposed parameters, links, etc...
In the example here we want to create a new target inside the exposed parameter that control the color of the UniformLeft
so we use the sourceElements() function to get the target and take it's parent ( the exposed color parameter)
now we can add a new target that we link to the color of the UniformRight
There also is a low level function that returns the pointers to this Object
