file: prepare_print_win32_vector.py
This extension will pre-process a vector image by applying the operations:
'EditSelectAllInAllLayers' and 'ObjectToPath'
before applying the extension: 'Win32 Vector Print'.
Generate vector graphics printout, specifically for Windows GDI32.
Copyright (C) 2014 Ryan Lerch (multiple difference)
2016 Maren Hachmann <marenhachmannATyahoo.com> (refactoring, extend to multibool)
2017 Alvin Penner <penner@vaxxine.com> (apply to 'Win32 Vector Print')
This code is based on 'inkscape-extension-multiple-difference' by Ryan Lerch
see : https://github.com/ryanlerch/inkscape-extension-multiple-difference
also: https://github.com/Moini/inkscape-extensions-multi-bool
It will call up a new instance of Inkscape and process the image there,
so that the original file is left intact.
