title: UIPopoverController's content view size
body: <p>I have a UIPopoverController that I present from a CGRect on iPad like so:</p>
  
  <pre><code>MarkersPopViewController *markersPop = [[MarkersPopViewController alloc] initWithNibName:@"MarkersPopView" bundle:nil];
  self.TestPopoverController = [[[UIPopoverController alloc] initWithContentViewController:markersPop] autorelease];
  [TestPopoverController presentPopoverFromRect:CGRectMake(20, 20, 700, 500) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES];
  </code></pre>
  
  <p>My MarkersPopView is the container view that has a UITableView that takes up the bulk of the .xib, and a UISegmentedControl just above the top of the UITableView.  The UITableView uses a custom subclass of UITableViewCell where each row is (700, 100).  </p>
  
  <p>When I run my app, the PopoverController is probably only 50 points wide and hugs the left side of the screen.  I'd like to make the view the right width for starters, and then center it.  Is there a reason why the UIPopoverController is so small?  I thought the UIPopoverController uses the default size of the content view if setPopoverContentSize: was not used.  Thanks.</p>
