Expose the extended window style on Window objects

[LeonarddeR]

Link to issue number:

None

Summary of the issue:

For application Windows, the window style can be fetched to find out whether the window has a title bar, is visible or unavailable. The extended window style wasn't yet available on Window objects. The extended window style provides information like:

• Whether the window supports dragging and dropping of files
• Whether the window is a window within an MDI interface
• Whether the window text is displayed using right-to-left reading-order properties
• Whether the window is a floating toolbar
• Whether the window is transparent
• The window is always on top

Description of how this pull request fixes the issue:

Implements the extendedWindowStyle property and adds it to the developer info

Testing performed:

Tested using several windows. IN many cases, the extended window style is 0. However, not for the notepad foreground window, for example.

Known issues with pull request:

None

Change log entry:

• Changes for developers
  • The extended window style of a window is now exposed using the extendedWindowStyle property on Window objects and their derivatives.
