Undoes the effect of a previous call to scare_mouse(), restoring the
original pointer state.
+void scare_mouse_area(int x, int y, int w, int h);
+ Helper for hiding the mouse pointer prior to a drawing operation. This
+ one acts like scare_mouse except the mouse will be hidden only if the
+ specified rectangle overlaps with the mouse pointer. Otherwise, the mouse
+ will be frozen. In other words, when drawing to the screen, pass the outer

extern int freeze_mouse_flag;
If this flag is set, the mouse pointer won't be redrawn when the mouse
moves. This can avoid the need to hide the pointer every time you draw to
