title: Change size of ToolStripMenuItem
body: <p>I'm custom drawing a menu item in a <code>MenuStrip</code>. The problem I'm having is that the menu item insists on sizing itself based on the text, which is not what I want (there is no text). I can set <code>AutoSize</code> to false and explicitly specify a size, but the containing menu (<code>ToolStripDropDown</code>) still sizes itself based on the text, which causes it to be too small to contain the entire menu item. </p>
  
  <p>Is there a straightforward way to set the size of a menu item?</p>
