Page units

[mooomooo]

Right now, there's no way of specifying absolute dimensions i.e. units. This should be fairly straightforward according the SVG spec; see, e.g.:

• https://stackoverflow.com/questions/1346922/svg-and-dpi-absolute-units-and-user-units-inkscape-vs-firefox-vs-imagemagick/2306752#2306752

Perhaps a simple way of incorporating this feature would be to add a new argument / member variable units="" to Drawing.__init__, then updating:

• drawsvg/drawsvg/drawing.py

  Line 243 in 2ab4c53

  width=img_width, height=img_height,

  
  to:

width=f"{img_width}{self.units}", height=f"img_height}{self.units}",

I stumbled upon this as well.
Here's my rather ugly workaround:

class MyDrawing(draw.Drawing):
    def __init__(self, width_mm, height_mm):
        super().__init__(width_mm, height_mm)
        self.width = f"{width_mm}mm"
        self.height = f"{height_mm}mm"
