also, it should take care of optional width and height params:

- if width is given, then your code should calculate height as width/aspect
- if height is given, it should calculate width as height*aspect
- if both width & height given, it should check both cases, and choose the
  one which fits to the width*height window:
     if(height*aspect>width)
        height=width/aspect
     else
        width=height*aspect
