   This combines the effects of dp_reflect and dp_refract to simulate a water\r
   surface. However, the refraction and the reflection are mixed using a Fresnel\r
   equation that makes the amount of reflection slide from reflectmin when\r
   looking parallel to the water to reflectmax when looking directly into the\r
   water. The result of this reflection/refraction mix is then layered BELOW the\r
   texture of the shader, so basically, it "fills up" the alpha values of the\r

+  the water transparent; but if r_water is 0, alpha isn't used, so the water can\r
