Hi, I'm looking into using Multisampled Coverage in FBOs in our application, and I've run into an interesting snafu. According to the extension specification coverage_samples cannot be larger than color_samples. This is enforced in OSG in two places: osgUtil/RenderStage.cpp(352) and osg/FrameBufferObject.cpp(254). However, those two places take opposite actions to resolve the issue.
The first one, osgUtil/RenderStage.cpp(352), decreases colorSamples to match (coverage)samples. The second one, osg/FrameBufferObject.cpp(254), increases (coverage)samples to match colorSamples. I haven't looked too hard at the code around this, but shouldn't this check only happen in one place (presumably FrameBufferObject.cpp)? RenderStage.cpp seems to lead into FrameBufferObject.cpp anyway, so it's doing a redundant check. I'm looking forward to hear your thoughts on this.
