OLCI PixelGeoCoding might give invalid pixel positions on request although latitude and longitude bands contain valid data
Description
This behaviour can be observed when creating a subset on base of a geometry that partially overlaps the input product. The intersections between the request geometry and the product boundaries will be computed, but for the intersection points no valid data is retrieved. This causes that only pixels safely within product bounds will be considered, resulting in a significantly smaller subset. The reason is that an unnecessary mask is passed on to the geocoding.
