priority

size_t osmscout::LabelPriority::priority {std::numeric_limits<size_t>::max()}

LabelPriority is used to determine the order of labels and to decide which label to show when there is a collision.

• priority is defined by the stylesheet
• basemap flag is here to give precedence to labels from ordinary map databases before world overview (basemap)
• ref is used for providing stable output for two labels with the same priority (and basemap flag) Priority from the stylesheet
