#129 Running dxf2code quitely opens a window

[Nikita Letov]

Running dxf2code quitely without GUI still invokes GUI for a brief moment. It is impossible to call help with dxf2code --help or run it quitely with dxf2gcode --quiet.

It has been tested on a Linux machine without any window manager (no way to open a window there, only terminal exists) and dxf2gcode won't work there even if ran quietly. Here's what the error looks like:

$ dxf2gcode -h
qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.

Running dxf2gcode with --quiet flag is not really quiet. It needs to open GUI for a brief moment to initialize graphic objects.
Thus, if you want to run with no physic display, run it with a virtual display like xvfb

On linux:

# Install and start xvfb
$ sudo apt update -y && apt install xvfb
$ Xvfb :1 -screen 0 1024x768x16 & 

# Set pernament environments
export QT_DEBUG_PLUGINS=1
export QT_QPA_PLATFORM=xcb
export DISPLAY=:1

It worked well, i was tested
