	Bounds Scale


	Inputs:

a bounding box and a scale factor


	Outputs:

a scaled bounding box

Implementation

01  function bounds_scale( bounds, factor )
02    dim min: min = bounds( BOUNDS_MIN )
03    dim max: max = bounds( BOUNDS_MAX )
04    dim cnt: cnt = vertex_middle( min, max )
05    bounds_scale = bounds_new( _
06      vertex_new( _
07        ( min( VERTEX_X ) - cnt( VERTEX_X ) ) * factor + cnt( VERTEX_X ), _
08        ( min( VERTEX_Y ) - cnt( VERTEX_Y ) ) * factor + cnt( VERTEX_Y ), _
09        ( min( VERTEX_Z ) - cnt( VERTEX_Z ) ) * factor + cnt( VERTEX_Z )  _
10      ), _
11      vertex_new( _
12        ( max( VERTEX_X ) - cnt( VERTEX_X ) ) * factor + cnt( VERTEX_X ), _
13        ( max( VERTEX_Y ) - cnt( VERTEX_Y ) ) * factor + cnt( VERTEX_Y ), _
14        ( max( VERTEX_Z ) - cnt( VERTEX_Z ) ) * factor + cnt( VERTEX_Z )  _
15      )  _
16    )
17  end function
