Comment 18 for bug 1015572

> Works as expected here (…)

Minor issues on Inkscape's side (based on my limited tests):
1) Current Inkscape trunk gives me this warning during building (compiler: llvm-gcc-4.2 from Xcode 4.3.2):
  CXX extension/internal/vsd-input.o
../../src/extension/internal/vsd-input.cpp: In member function ‘void Inkscape::Extension::Internal::VsdImportDialog::_onPageNumberChanged()’:
../../src/extension/internal/vsd-input.cpp:189: warning: comparison between signed and unsigned integer expressions
2) Inkscape seems to have trouble with some filter effects in imported newer file formats (the filtered objects don't render visible on-canvas in normal view mode). I haven't investigated this further beyond some comparisons with other SVG viewers (which indicated that it's likely an issue with Inkscape's SVG filter support).

Minor issues with libvisio's SVG output:
3) Stroke widths sometimes are so thin that expected lines are not visibly rendered on-canvas in Inkscape at reasonable zoom-levels.
4) AFAICT some of the features of Visio files aren't yet fully supported in libvisio's SVG output (e.g. multi-line text, markers).
