... well, let's call it "work in progress".
The problem I have now is that I don't have the source code of midori. (The enhancements to the djvu viewer were only possible because I found the source code of the previous version ... but there is no "previous" verison of the browser.)
It would be this following line and the window would be rotated and filling the screen.
Code:
gtk_window_resize (GTK_WINDOW (window), sw, sh);
Right now it is only rotated but it has the dimensions of the old window. Which is really no improvement at all. It is good progress but I worry that now I'm stuck until the source code is released.
