m_InitCalled is set by Init(), so Init() is only called once. I also tried
using FLTK's valid(), but it does not make a difference.
Considering calling make_current(), I first tried without calling it
explicitly, but the context is not set correctly. I then tried calling it
explicitly but without success.
And I don't call draw() directly, I only call redraw() so that should be ok.
This leaves me clueless why fl_window and fl_gc are not set correctly. Is there
any way to debug this?
