/**
* The ForegroundTarget class defines targets based on whether they have
* textures (as opposed to textureless background). This class can be used to distinguish between foreground targets and
* the background target.
* For example, if you have a solid black background image that contains a small white square, you can use
* this ForegroundTarget class to find the white square in the black background image without having to specify the image of the
* white square the target.
