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 you can customize build process by using 'make'.
Sometimes special steps need to be done to build entire project.
But it's not necessary to create another target in Beremiz every time you need to customize something in build process. Just use for that 'Generic' target and describe all necessary steps in Makefile.
For example, you can
- preprocess generated by Beremiz C source files,
- do some fancy source code transformation using any tools you want,
- use any compiler you want,
- call static analyzers,
- run integration tests on the project,
- upload source code to external build server,
- upload to the target and compile it there,
- flash/transfer your compiled binary to the target,
and much much more.
