This patch begins the support for the 'view-box' attribute that can be attached to <svg>'s. The FormattingContext determines the size of the Element according to the specified 'width' and 'height' or if they are not given by the 'viewbox' or by the bounding box of the path if nothing is specified. When we try to paint a SVG Path that belongs to a <svg> that has the 'view-box' and a specified 'height'/'width', all the parts of the path get scaled/moved accordingly. There probably are many edge cases and bugs still to be found, but this is a nice start. :^)
