[PATCH 2/2] wxwidgets 3.0: move FONT_* construction to SpectFrame When using wxWidgets 3.0, creating a wxFont requires the gtk+ library to be initialized. This is causing espeakedit to segfault.
SpectFrame::Draw is the only place where the FONT_* variables are used, so move them into the SpectFrame class and create them in the constructor.
Also, FONT_NORMAL is not used so it has been removed.
