    <-|INDEX|->
Rotates the view around the Y axis (absolute rotation).

### FORMAT

      #include <Ninja.h>

      void njRotateViewY(*v, ang)
      NJS_VIEW *v
      Angle ang

### PARAMETERS

NJS_VIEW *v
  view structure pointer
Angle ang
  rotation angle (absolute amount of rotation)

### RETURN VALUE

  None

### FUNCTION

- Rotates the view around the Y axis.

### EXAMPLE

  Rotates the view located at (0, 0, 3000) with orientation (0, 0, -1) (behind the screen) by 90 degrees around the Y axis.

      #define VIEW_PX 0.f
      #define VIEW_PY 0.f
      #define VIEW_PZ 3000.f
      #define VIEW_VX 0.f
      #define VIEW_VY 0.f
      #define VIEW_VZ -1.f
      #define VIEW_ROLL 0

      NJS_VIEW v;

      v.px = VIEW_PX;
      v.py = VIEW_PY;
      v.pz = VIEW_PZ;
      v.vx = VIEW_VX;
      v.vy = VIEW_VY;
      v.vz = VIEW_VZ;
      v.roll = NJM_DEG_ANG(VIEW_ROLL);

      njSetView(&v);
      njRotateViewY(&v, NJM_DEG_ANG(90));
      njClearMatrix();

### NOTES

- When parameter v is NULL, the current view is rotated.
- Views (viewpoints) can be moved and rotated by manipulating the view structure.
