[Devel] [bug?] FT_Vector_Rotate

[Joseph Koshy]

The description of 'FT_Vector_Rotate' in the HTML documentation
has a function prototype:

  FT_EXPORT( void )
  FT_Vector_Rotate( FT_Vector*  vec,
                    FT_Angle    angle );

However the description describes 'angle' as:

 angle   The address of angle.

Either way, I seem to be missing something since I'm not getting the
results that I'm expecting.  For example, rotating a vector [x = 1, y = 0] 
by 90 degrees does not result in a new vector [x = 0, y = 1].

$ ./a.out
old v1 = [1.0, 0.0]
new v1 = [-1.63, 0.63]

The test program is enclosed.  How *does* one use FT_Vector_Rotate?
