Hi,

   i have two question regarding FBO and Stencil buffer. Perhaps someone
could clear my thoughts.

   1) Does OSG 2.6.1 supports FBO with stencil buffer attachment?

   2) Does it supports EXT_PACKED_DEPTH_STENCIL?


Explanation: I use FBO to take the render. Recently i wanted to use stencil
to render concave polygons. But it doesn't work. It seems that i must also
attach the stencil buffer. But don't know exactly how to achieve that and
i'm getting a FBO setup failed (0x8cd6) from runCameraSetup. The graphics
card supports PACKED_DEPTH_STENCIL and it seems i must also attach a depth
buffer but i don't know how.

Now i'm lost and a bit confused with all this mess of buffers. Any help
about it will be really appreciated.

Thanks in advance and best regards
Himar.
