title: Hide window resize button
body: <p>When creating an <code>NSWindow</code> that has the <code>NSResizableWindowMask</code> flag set, Cocoa always draws a resize button in the bottom-right hand corner of the window. This button doesn't integrate very nicely with my custom drawn UI graphics so I'd like to know: Is there a way to tell Cocoa not to draw this button but still keep my window resizable?</p>
