title: Change mouse cursor to standard hand cursor in XCB
body: <p>Using XCB, I need to change the mouse pointer for a window to the standard hand cursor (whatever that means in Linux, I need a toolkit-independent solution).</p>
  
  <p>Note: loading the "cursor" font and changing the window attribute XCB_CW_CURSOR to XC_hand2 is not a solution. This loads the X11 ugly and unfamiliar hand cursor, not the default Ubuntu hand cursor that you see in Chrome when you hover links.</p>
  
  <p>Thanks.</p>
