Window decorations: Title bar customizing

[DevCharly]

(work in progress)

Purpose of this PR is to improve customizing of title bar in FlatLaf window decorations (usually used on Windows 10/11).

Done

• hide window title, iconify, maximize and close buttons
• hide window icon (since FlatLaf 2.0)
• change title bar background/foreground (since FlatLaf 1.1.2)

To do

• fullWindowContent option (similar to macOS https://www.formdev.com/flatlaf/macos/#full_window_content)
• optionally place iconify, maximize and close buttons on left side (in reverse order), useful if fullWindowContent is enabled
• specify areas where the user can click-and-drag window (if fullWindowContent is enabled)
• TBD

How to

Hide window icon or title

frameOrDialog.getRootPane().putClientProperty( FlatClientProperties.TITLE_BAR_SHOW_ICON, false );
frameOrDialog.getRootPane().putClientProperty( FlatClientProperties.TITLE_BAR_SHOW_TITLE, false );

Hide iconify, maximize/restore or close button

frame.getRootPane().putClientProperty( FlatClientProperties.TITLE_BAR_SHOW_ICONIFFY, false );
frame.getRootPane().putClientProperty( FlatClientProperties.TITLE_BAR_SHOW_MAXIMIZE, false );
frameOrDialog.getRootPane().putClientProperty( FlatClientProperties.TITLE_BAR_SHOW_CLOSE, false );

Change title bar background/foreground

frameOrDialog.getRootPane().putClientProperty( FlatClientProperties.TITLE_BAR_BACKGROUND, Color.green );
frameOrDialog.getRootPane().putClientProperty( FlatClientProperties.TITLE_BAR_FOREGROUND, Color.blue );
