Fix regression with SVG that would be rendered smaller than one pixel

[stephanr]

This PR prevents errors when SVG should be rendered to a size smaller than one pixel.
Probably one of the last batik version updates introduced this issue.

Without this workaround, the following exception occurs:

org.apache.batik.transcoder.TranscoderException: null
Enclosed Exception: 
negative or zero width

Manual tests on existing workspaces showed that even a sub pixel image won't turn into rendering problems as 1×1 images are ignored or rendered correctly scaled (smaller).
