fix issue with printing scheme (FBD, LD or SFC) with comment element on GNU/Linux
If you draw FBD scheme and place comment on it and then try to print
it, then no wires will be printed and comment box is empty (text is
missing). This happens only for wx.PrinterDC and not on wx.MemoryDC
that is used to draw print preview window in Beremiz IDE.
Looks like a bug in wxPython or wxWidgets.
There were found several workaround for this issue.
1) If some dc.DrawLines call is placed before dc.DrawPolygon, then the
problem is gone.
...
dc.DrawLines(polygon)
dc.DrawPolygon(polygon)
...
2) Reseting DC brush solves the problem as well (see this changeset).

<xhtml:p><![CDATA[This example shows how IEC program in PLC can interact with web interface.
svgui is extensions to build web interface to PLC. It has *integrated* web-server. So it's NOT necessary to install Apache, lighttpd or nginx for that!!!
As the program is running in PLC, web UI will be available at http://localhost:8009/.
Web interface is build as SVG file in Inkscape. To edit SVG file click 'Inkscape' button in 0x: svgui extension.
Inkscape is a free and open-source vector graphics editor. It's not part of Beremiz and needs to be installed separately.

Back_id and sele_id inputs of these blocks are IDs of graphic primitives in SVG file.
This is the way how elements in SVG are bound to elements in PLC program.
You can find out or edit these IDs in Inkscape.]]></xhtml:p>
