To subscribers of the xforms list

I am very happy to see that Xforms and this mailing list are still alive.

I have developped since several years a data visualization application
that uses Xforms as GUI. In some circumstances, I would like to run this
application in background (producing just jpg files, without user
interaction and without showing any xform window) on a machine which has
no display. But I get stucked on the fl_initialize function.
With the following error message:
     Can't open display --No such file or directory
     Missing or failed fl_initialize()

For now, I have overcome the problem by using xvfb when starting the
application. But could the next release of Xform provide an API or a flag
that allows to run temporarily without display?
Or could the next release separate in fl_initialize what is specific xform
init from what is related to the display?

Thank you,
