    • width, height
    • points
    • d

Apply transformations

Applies transformations to elements so the attribute can be removed.

    • In the form

      • comma: (12,34)
      • space(s): (12 34)
      • comma and space(s): (12, 34), (12 ,34), (12 , 34)
      • decimal: (1.2, 3.4)
      • negative: (-1.2, -3.4)
    • Shapes

      • line
      • rect
      • circle, ellipse
      • polyline, polygon
      • path (not fully tested)
      • g (not fully tested)
  • Scale

CSS styling

Need to check whether style element already exists and whether class names already exist.
Ideally find most efficient way to class elements for styling.
