/**

 * This structure represents a directional range of the content. It is defined
 * by two points in the content, where each one is defined by an accessible
 * object and an offset relative to it. A typical case of a range point is
 * a text accessible and text offset within it.
 *
 * The "anchor" is one point of the range and typically remains constant.
 * The other point is the "active" point, which typically corresponds to
 * the user's focus or point of interest. The user moves the active point to
 * expand or collapse the range. In most cases, anchor is the start of the range
 * and active is the end. However, in a case of selection, when selecting
 * backwards (e.g., pressing shift+left arrow in a text field), the start of
 * the range is the active point, as the user moves this to manipulate
 * the selection.
