Comment 2 for bug 1811982

Hi Jeff-

After this change, eeschema no longer saves the fallback state. If I edit the config file to be canvas_type=2, I can get cairo to start on open. But if I select OpenGL (when not supported), I get the message saying "Could not use OpenGL, falling back to software rendering". But it saves canvas_type=1 and gives me the same message again on starting next time. Apart from editing the config file, I can no longer get it to save Cairo as my default.
