Ok. Try the attached files. I'm not really happy with the 
implementation. The design of Morphic allows for different drawing 
canvases, but not really for switching between them during drawing. So, 
what I'm sending here is rather hacky.

Still, you can try the script below. Please set a TrueType font before 
trying this. Also, do Feature require: 'SVG'. Try this is an image 
without unsaved work. It is likely you'll need to kill it, for instance 
by using the halos.

w _ VectorGraphicsPasteUpMorph new openInWorld morphExtent: 1000 at 800.
[
[
     m _ SVGMainMorph fromFileNamed: 'VectorGraphics/SVGSamples/lionx.svg'.
] on: SVGWarning do: [ :warning | warning print. warning resume ]
] on: PathCommandError do: [ :error | error print. error return ].
w addMorph: m.
w addMorph: EllipseMorph new.
w addMorph: BorderedRectMorph new.
w addMorph: RectangleLikeMorph new.

I hope this helps you get a feel of what can be done.

Cheers,
