[PD] using pix objects on rendered graphics in gem

[chris clepper]

Fragment shaders can be used for such an effect.  Also, the 'soften' effect
can be done by rendering the geometry several times and offsetting the
coordinates slightly.  If you have lots of geometry to render another option
involves using pix_snap2tex after everything is drawn then applying that
texture to several offset rectangles.
