[PD] fsaa with intel gma950 / OS X?

Either the Intel GPU doesn't support FSAA at all or turning it on reverts to
software rendering.  The former is possible since the GPU has so little
power to begin with.  GEM doesn't support software rendering on OSX and
there is a chance that something fails silently and then goes back to
'hardware' rendering.  The Intel chip only does a tiny amount of actual
hardware rendering for the pixel pipeline and almost nothing for the vertex
although testing reports full hardware OpenGL functions.

The anti-aliasing done by the text objects is a very old type of AA which is
disabled on Nvidia and ATI parts in favor of FSAA.  If that works you can
try the [polygon_smooth] object before any geometry drawn.
