A quick & easy-to-use heat haze shader!
Works with GMS 1.x and 2.x.
To start implementing the heat haze, use
haze_start(). You can add specific circular areas using
haze_circle_add() and rectangular areas using
haze_rect_add(). You can also make it cover the whole screen.
For more info, read the documentation present inside the scripts.
