Comment 10 for bug 904958

Note, title-less maximization is already covered by EWMH, so this needs to be implemented via the standard, making it an unconditional option in not the right way to add this feature.

1. add support for EWMH standard for borderless maximization
2. make sure it's not just the title, but border as we'll (ie there is already an option to show or hide borders on maximization, make sure this work in any case)
3. once the feature supports the standard, we can add a user option to set the default behaviour, for apps that don't specify their desired maximization mode via the standard.
