title: using grid.SetCellAlignment in python
body: <p>I have a grid in wxpython and I want to show all text in center of cells.</p>
  
  <p>From what I can tell this is doable with </p>
  
  <p><code>grid.SetCellAlignment(0, 0, wx.ALIGN_CENTRE, wx.ALIGN_CENTRE)</code></p>
  
  <p>However as you can see this is local property of cell. How can I do that for the whole grid?</p>
