This is not a problem. I can add option for that to ZoomWidget.
One thing what you can’t do with current implementation is that white border around characters, because I stream to widget’s background. This is the efficient way. Solution is streaming to foreground and you can setup background. This is not efficient way, because people will create big background textures (with current implementation) – and only because they need tin border. If your background will be pure color then I can fix it easily, opengl does it fine. for images I can do partial fix, but it will work fine.
