title: Button TextImageRelation and TextAlign problem
body: <p>When using a Button in my projects... they expose a property called <code>TextImageRelation</code>. This is used to tell the control where to place the button image in relation with the text (I'm using the ImageBeforeText option).  Now, I need to have the text aligned to the center.</p>
  
  <p>The logic outcome I would spect is: an image aligned to the left and the button text centred in the space between the image and the right border of the button.</p>
  
  <p>But not...  the text is aligned next to the image OR aligned to center but not taking into account the image (not sure which case).</p>
  
  <p>There is a way to change this behavior?</p>
