+ * The projection will always start from the grid (y1,x1), and will travel
+ * towards the grid (y2,x2), touching one grid per unit of distance along
+ * the major axis, and stopping when it enters the destination grid or a
+ * wall grid, or has travelled the maximum legal distance of "range".
+ *
+ * Note that "distance" in this function (as in the "update_view()" code)
+ * is defined as "MAX(dy,dx) + MIN(dy,dx)/2", which means that the player
+ * actually has an "octagon of projection" not a "circle of projection".
+ *
+ * The path grids are saved into the grid array pointed to by "gp", and
+ * there should be room for at least "range" grids in "gp". Note that
+ * due to the way in which distance is calculated, this function normally
+ * uses fewer than "range" grids for the projection path, so the result
+ * of this function should never be compared directly to "range". Note
+ * that the initial grid (y1,x1) is never saved into the grid array, not
+ * even if the initial grid is also the final grid.
+ *
+ * The "flg" flags can be used to modify the behavior of this function.
+ *
+ * In particular, the "PROJECT_STOP" and "PROJECT_THRU" flags have the same
+ * semantics as they do for the "project" function, namely, that the path
+ * will stop as soon as it hits a monster, or that the path will continue
+ * through the destination grid, respectively.
+ *
+ * The "PROJECT_JUMP" flag, which for the "project()" function means to
+ * start at a special grid (which makes no sense in this function), means
+ * that the path should be "angled" slightly if needed to avoid any wall
+ * grids, allowing the player to "target" any grid which is in "view".
+ * This flag is non-trivial and has not yet been implemented, but could
+ * perhaps make use of the "vinfo" array (above).
+ *
+ * This function returns the number of grids (if any) in the path. This
+ * function will return zero if and only if (y1,x1) and (y2,x2) are equal.
+ *
+ * This algorithm is similar to, but slightly different from, the one used
+ * by "update_view_los()", and very different from the one used by "los()".
