/**
* The OverlapBehavior element tells a system how to behave when multiple
* raster images in a layer overlap each other, for example with
* satellite-image scenes. LATEST_ON_TOP and EARLIEST_ON_TOP refer to the
* time the scene was captured. AVERAGE means to average multiple scenes
* together. This can produce blurry results if the source images are
* not perfectly aligned in their geo-referencing. RANDOM means to select
* an image (or piece thereof) randomly and place it on top. This can
* produce crisper results than AVERAGE potentially more efficiently than
* LATEST_ON_TOP or EARLIEST_ON_TOP. The default behaviour is
* system-dependent.
*
* @return LATEST_ON_TOP, EARLIEST_ON_TOP, AVERAGE or RANDOM
