Hi all,

I've been wondering why my settings for multi-sampled anti-aliasing
were being ignored since porting my GUI code to Qt.  I've since
discovered the same behavior in the osgviewerQT example.

Since this program does not accept the --samples argument I altered
QOSGWidget::createContext to explicitly set:
ds->setNumMultiSamples( 4 );

Where we choose a visual in osgViewer::GraphicsWindowX11 I've confirmed that
the visual number in the visual info indicates 4 samples...

   visual  x  bf lv rg d st colorbuffer ax dp st accumbuffer  ms  cav
 id dep cl sp sz l  ci b ro  r  g  b  a bf th cl  r  g  b  a ns b eat
----------------------------------------------------------------------

0x30 24 tc  0 32  0 r  y  .  8  8  8  0  4 24  0 16 16 16 16  4 1 Ncon

However, there are jaggies all over the place -- no appearant anti-aliasing.
Does anyone have an idea why this is so?
