Exporting to SVG using the SVG Cairo exporter is broken.

[massimo-nocentini]

I'm writing from an Ubuntu (22.04 LTS) box and I'm trying to isolate an example about the exporting to SVG files using the Cairo SVG exporter: The problem that I've found is that the latest master branch yields a wrong exporting. The following steps can be used to reproduce my problem:

1. Get a fresh image and the vm with curl https://get.pharo.org/64/110+vm | bash;

2. then open it with ./pharo-ui, open a Playground and evaluate the following code:

   Metacello new
   baseline: 'Roassal3Exporters';
   repository: 'github://ObjectProfile/Roassal3Exporters';
   load.
   
         pango := (RSLabel new
                       text: 'hello world';
                       yourself) .
   
         another := (RSLabel new
                         size: 14;
                         text: 'Mickey Mouse';
                         yourself).
   
         RSLocation new above move: pango on: another.
   
         c := RSComposite new
                  shapes: (RSGroup new
                           add: pango;
                           add: another;
                           yourself);
                  "translateTo: 100 asPoint;"yourself.
   canvas := RSCanvas new.
         canvas add: c.
   
       canvas svgCairoExporter zoomToShapes ;export.

   that should produce a good SVG image

with the two small labels.

3. evaluate then the following chunk that loads the latest master branch:

   [Metacello new
   baseline: 'Roassal3';
   repository: 'github://ObjectProfile/Roassal3';
   load: 'Full' ] on: MCMergeOrLoadWarning do: [:warning | warning load ].

4. then re-evaluate the chunks:

   pango := (RSLabel new
                       text: 'hello world';
                       yourself) .
   
         another := (RSLabel new
                         size: 14;
                         text: 'Michey Mouse';
                         yourself).
   
         RSLocation new above move: pango on: another.
   
         c := RSComposite new
                  shapes: (RSGroup new
                           add: pango;
                           add: another;
                           yourself);
                  "translateTo: 100 asPoint;"yourself.
   canvas := RSCanvas new.
         canvas add: c.
   
       canvas svgCairoExporter zoomToShapes ;export.

   which produces a wrong image on my machine
