Robert Osfield 4457d2a145 From Colin McDonald, "Upgrading to OpenSceneGraph 3.0.1, texture mip mapping stopped ... working on some junk low-end graphics cards which I still have to support. They worked ok with osg 2.8 and earlier. The problem turned out to be with gl proxy textures, which are unreliable on those devices. Proxy textures are used by the glu mipmap build routines to determine if a texture size is supported. The external glu library had a nice fallback behaviour, so that if proxy textures didn't work then the mipmap texture was still created. But in the work on the new embedded glu routines that fallback behaviour has been inadvertently lost. I have restored the fallback in src/osg/glu/libutil/mipmap.cpp. It doesn't add any extra complexity."		2012-02-10 17:20:43 +00:00
