Description
This function is used to add a custom refresh rate to the CRTC database for a device. By default a standard databse of known display modes is available, but this function allows the user to create custom refresh rates and add those to the SNAP drivers.
Unless you pass a value of true to the saveToDisk parameter, the changes will only affect the currently loaded copy of SNAP and will not affect new versions of SNAP that are loaded from disk. To make the change permanent, you need to set this parameter to true.
