Prior to Vuforia 6, the scanner showed scan points/dots while scanning, along with a scan line.

The scan point color could be changed with a call to targetFinder->setUIPointColor(red, green, blue)

In the Core Features sample for this new SDK, I found some sample code that can allow an app to add the scan line that is no longer built into the SDK.   See scanlineCreate, scanlineStart, scanlineStop in CloudRecoViewController.mm.

I could not find any sample code to allow the app to add the scan points/dots that were built into the previous SDK.   Can someone suggest how this can be added?
