)extrude operation of a 2D SDFs into a 3D one

Use:

```
<float> opExtrude( in <vec3> p, in <float> sdf, in <float> h )
```

```
#ifndef FNC_OPEXTRUDE
#define FNC_OPEXTRUDE
float opExtrude( in vec3 p, in float sdf, in float h ) {
vec2 w = vec2( sdf, abs(p.z) - h );
return min(max(w.x,w.y),0.0) + length(max(w,0.0));
}
#endif
```

Use:

```
<float> opExtrude( in <float3> p, in <float> sdf, in <float> h )
```

```
#ifndef FNC_OPEXTRUDE
#define FNC_OPEXTRUDE
float opExtrude( in float3 p, in float sdf, in float h ) {
float2 w = float2( sdf, abs(p.z) - h );
return min(max(w.x,w.y),0.0) + length(max(w,0.0));
}
#endif
```

Use:

```
<float> opExtrude( <float3> p, <float> sdf, <float> h )
```
