Helper for hiding the mouse cursor before drawing in an area. allegro game programming library.
#include <allegro.h>
void scare_mouse_area(int x, int y, int w, int h);
Like scare_mouse(), but will only hide the cursor if it is inside the specified rectangle. Otherwise the cursor will simply be frozen in place until you call unscare_mouse(), so it cannot interfere with your drawing.
