[Mono-winforms-list] button implmentation

[Jonathan Gilbert]

Just thought I'd poke my head in on this and point out that the Windows
implementations usually don't actually draw themselves. They simply wrap up
a win32 HWND and allow the system to draw the control.

The other thing to point out is that Microsoft codes in this pattern:

public event PaintEventHandler Paint;

protected void OnPaint(PaintEventArgs e)
{
  if (Paint != null)
    Paint(this, e);
}

Therefore, it is likely that a subclass would hook the 'Paint' event
instead of overriding the 'OnPaint' method.
