    Description

      When using a QGLWidget in a QMdiArea (as a QMdiSubWindow), the stacking of the widgets are wrong on Mac/Cocoa. Works on Carbon because we use AGL_BUFFER_RECT to clip the QGLWidget ourselves. It seems this is not really supported in the Cocoa API, but a workaround would have been nice.


      Possible solution: sort the MdiSubWindows using [NSView sortSubviewsUsingFunction:context]
