* interesting, all terrain features except floors (and invisible traps) are
* interesting, and floors (and invisible traps) are interesting sometimes
* (depending on various options involving the illumination of floor grids).
*
* The automatic memorization of all objects and non-floor terrain features
* as soon as they are displayed allows incredible amounts of optimization
* in various places, especially "map_info()" and this function itself.
*
* Note that the memorization of objects is completely separate from the
* memorization of terrain features, preventing annoying floor memorization
* when a detected object is picked up from a dark floor, and object
* memorization when an object is dropped into a floor grid which is
* memorized but out-of-sight.
*
* This function should be called every time the "memorization" of a grid
* (or the object in a grid) is called into question, such as when an object
* is created in a grid, when a terrain feature "changes" from "floor" to
* "non-floor", and when any grid becomes "see-able" for any reason.
*
* This function is called primarily from the "update_view()" function, for
* each grid which becomes newly "see-able".
