        Right.

        So - unfortunately on Windows & Mac we initialize VCL for those tests
which I imagine creates an invisible window (for it's event loop) and
other more or less evil & non-desired stuff.

        Having said that, it normally doesn't popup dialogs and shouldn't
interfere with the UI - what are you seeing ?

        The main reason (IIRC) is that the font logic is not available outside
of the unix / freetype world and that is needed for the headless /
generic code, and until we either split out the font handling to be
better abstracted, or ship freetype cross-platform we'll have to do this
way I IIRC.

        Work appreciated to improve the vcl/generic split etc. :-)

        HTH,

                Michael.
