I have two `ToolBar`s side by side (I had to do that so I could align buttons right and left)
But now, I have to add some text that can be aligned right left or center between both toolbars. I added the text in a `TextBlock` inside a `StackPanel` disposed on a `Grid` at the second position (between the toolbars) and, of course, it created a gap between both toolbars (A stackPanel doesn't have the same style as a toolbar, of course).

I would like to replicate the toolbar `LinearGradientBrush` on my stackpanel so it looks the same as my toolbar does. the point is to make the thing look like ONE toolbar. 

Is there a way to get the `ToolBar` `Style` or to recreate it with a `LinearGradientBrush` definition, and if so, how?
