I think it is fine. However, I would avoid introducing 2 more converters
and instead I would modify convertDefault.py so that when imagemagick is
not installed the new imgconvert command is used.

In this way, whatever conversion between image formats supported by Qt
would succeed (without the need of new converter definitions).

 My question (again): how can I circumvent this and configure „my“ converter

 of the PDF (which would be rasterized anyway, when ImageMagick is used for
 SVG to PDF conversion).

Sorry, I made a last minute change and put a logic error in imgconvert.cpp.
The check for to pdf or not to pdf was wrong.

Here is the corrected version.
