Can I adjust to frame CLOSE btn ?

[oligamiq]

I customed titlebar, but there are 7px between CLOSE btn and frame.
My pc is windows 11 and windows 10 both.
I test some condition but cannot.

This is what enable with_enabled_buttons(WindowButtons::CLOSE).

This is what normal.

This project information.

Change frame size by DwmExtendFrameIntoClientArea.
Top is 40. Bottom is 10.

Blue color is Windows accent color.

If DwmDefWindowProc's hit_test failed, my hit_test use.
※hit_test Operate close, maximize, etc.

Ref #2384

I want to adjust to frame CLOSE btn.
I am also considering not use DwmDefWindowProc and rm close btn and upgrade my hit_test, but, I don't know rm close btn.

Set ControlBox false and rm close btn.
This is not win32api.
