Originally, most of the sources used constructor parameters to set the various options of the source. Although convenient, it was difficult to keep track of what each parameter meant. To make the code more clear, source parameters are now set with accessor functions (e.g. `SetPointDimensions`). Although this makes code more verbose, it helps prevent mistakes and makes the changes more resilient to future changes.
