Well, configs of some samples do answer your question. AFAIR.

The number of points was increased in 2.5.x two years ago. This is why
specifying fvwm version is always important.

I think this is in FAQ.

No, you may apply multiple AddButtonStyle as needed.

Well, you don't draw buttons very often to justify a complete syntax
error diagnostics system, do you? :)

It is 10000.

This is possibly because you use 3-d like relief that is 2 pixels wide.
If you use flat decorations, then entire 100% is available. I think.

No time to read/play with this config for now. Maybe later.
Or you may just post a screenshot url.
