/**
 * Represents an interaction (currently only mouse) event on a {@link PagePanel}.
 * To capture these events, implement the {@link PagePanelInteractionListener} interface
 * and register via the {@link PagePanel#addPagePanelInteractionListener PagePanel.addPagePanelInteractionListener()} or
 * {@link DocumentViewport#addPagePanelInteractionListener DocumentViewport.addPagePanelInteractionListener()} methods.
 * Be sure to check the {@link #getType} method to see what sort of event it is - current values
 * include:
 * <table class="defntable">
 * <tr><th>mouseEntered</th><td>Raised when the mouseEntered event is raised</tr>
 * <tr><th>mouseExited</th><td>Raised when the mouseExited event is raised</tr>
 * <tr><th>mousePressed</th><td>Raised when the mousePressed event is raised</tr>
 * <tr><th>mouseReleased</th><td>Raised when the mouseReleased event is raised</tr>
 * <tr><th>mouseClicked</th><td>Raised when the mouseClicked event is raised</tr>
 * <tr><th>mouseMoved</th><td>Raised when the mouseMoved event is raised</tr>
 * <tr><th>mouseDragged</th><td>Raised when the mouseDragged event is raised</tr>
 * </table>
