skybox fog calculations wrong

[klepto2]

When using the skybox together with the angular fog you get artifacts in the corners like this:

This can be fixed with something like this in the sky.frag:

	if (ExtractCameraFogSettings(CameraID, fogcolor, fogrange, fogangle))
		{
			float slope = degrees(asin(normalize(texCoords).y));
			if (slope < fogangle.y)
			{
				float l = clamp(1.0f - ((slope - fogangle.x) / (fogangle.y - fogangle.x)), 0.0f, 1.0f) * fogcolor.a;
				outColor[0].rgb = outColor[0].rgb * (1.0f - l) + fogcolor.rgb * l;
			}
		}

just normalize the texcoords before calculating the slope:

Fixed!
