NB: using the braced-initializer list uncovered an error here:
the float returned by std::floor() can't be implicitly cast to
an int. This is solved by using base::ClampFloor<int>() instead.
std::floor()
Closes https://github.com/electron/electron/issues/44569.
Fixes an issue where the WCO buttons were hidden on Linux in fullscreen mode
but not on Windows or macOS. The Windows behavior is the expected one, so this
commit makes the Linux behavior consistent.
Closes https://github.com/electron/electron/issues/43714.
Fixes an issue where the resizing border was not being handled correctly on Linux WCO
caption buttons. This is now taken into account as a part of the NonClientHitTest.
