示例1: Magnetize

/**
 * Function Magnetize
 * tests to see if there are any magnetic items within near reach of the given
 * "curpos".  If yes, then curpos is adjusted appropriately according to that
 * near magnetic item and true is returned.
 * @param frame = the current frame
 * @param aCurrentTool = the current tool id (from vertical right toolbar)
 * @param aGridSize = the current grid size
 * @param on_grid = the on grid position near initial position ( often on_grid = curpos)
 * @param curpos The initial position, and what to adjust if a change is needed.
 * @return bool - true if the position was adjusted magnetically, else false.
