How do WinForms controls inside WPF WindowsFormsHost remote?

Say, I have a WPF program with a Windows Forms control in "WindowsFormsHost" on some of its windows.

I use that pr开发者_JAVA百科ogram via Remote Desktop.

How will this control's graphics remote? Via GDI instructions as if it was WinForms app or as plain bitmaps like WPF does?

Created a test. So, it remotes as GDI, very fast.
