what would be useful is to find out the actual current screen resolution,
not the virtual screen. Otherwise, the touchscreen behaves as if covering
the whole virtual screen. I want just the visible screen. I don't think it
would be useful to know what the viewing window is. I'll check on that
modeline api, thanks.

I am surprised this has not been solved in other drivers though.
