Black canvas, Dia unusable under Windows 10
The software seems to work behind the black canvas, but formally, is unusable.
I compiled Dia under Windows 10 with mingw64 (within the package msys2).
The Dia log is the following (and it doesn't seems to report any particular error):
$ ./c/latest_dia/bin/dia.exe could not import diasvg_import.py [No module named math] could not import gtkcons.py [No module named pygtk] could not import pydiadoc.py [No module named math] ** (dia.exe:7100): WARNING **: 14:16:37.069: Unable to find object type: AADL - Box Canvas size change... ** Message: 14:16:38.091: Only antialias renderers supported
