Thanks, LGTM.

In my tests, I couldn't get it to resize dynamically my resolution, but
it might be useful to someone else.

To document my experience: it successfully resized the logical 
viewport, but didn't actually change the resolution of my panel. 
Considering this thing was written in a time of CRTs and before 
KMS, that's not unreasonable & might require some custom EDID 
hackery to do that.

Thanks,

T G-R
