title: Is it possible to combine an ImageBrush with a LinearGradientBrush in UWP
body: <p>I'm building a Planning Poker UWP app for fun.  I can style the poker cards (currently implemented as Buttons, via the Background property) using either an ImageBrush or a LinearGradientBrush without any issue, but obviously I can only set one type of brush to that property.</p>
  
  <p>I'd like to style the card with an image, which then had another brush (e.g. a LinearGradientBrush) over-layed on top, this other brush would naturally have some degree of transparency so that parts of the image could show through.</p>
  
  <p>How would you do that?</p>
  
  <p>For the actual poker card that the user sees - I can re-implement that fairly easily using a different control type (e.g. a UserControl that combined several controls, each with their own background) but there are other instances of use (i.e. showing a list of the available styles), so I wanted to see if there way another way before looking into writing a custom UserControl.</p>
