Problem Description
When using a frameless window and drawing a custom title bar, the native OS title context menu is missing. On Windows there is ways to still show it (via hookWindowMessage) but on Linux no such API seems to exist.

Proposed Solution
A way for controlling if the native OS title menu can show in custom title bars of frameless windows.
