Make CTabFolder more customizable

[ThoKalBaGoIT]

I want to customize the CTabFolder in my application to have a ToolBar with buttons for minimize, restore, and maximize, which should always be visible:

I managed to achieve this using setTopRight, but I had to copy a lot of code from CTabFolder and CTabFolderRenderer. It would be nice if more methods were accessible. Maybe the current minMaxTb toolbar implementation could be extracted for better customization?

Here’s an example of what I had to do to achieve my goal:
MyCTabFolderSnippet.java
MyCTabFolderWrapper.java
MyCTabFolderMinRestoreMaxRenderer.java
MyCTabFolderMinRestoreMaxListener.java

If there are any other options, please let me know.
