From Alexander Sinditskiy, "My changes added support for gltexstorrage2d for texture2d.
Initially I described issue in message: http://forum.openscenegraph.org/viewtopic.php?t=13820 It solves issue with compiling texture using ico from image with mipmaps I added enviroment variable OSG_GL_TEXTURE_STORAGE_ENABLE to control usage of glTexStorage2d. Initially it is disabled. It used only if image have mipmaps. Another issue is converting from internalFormat + type to sized internal format. I created sizedInternalFormats[] struct where sized internal formats are ordered from worse->best. also this struct have commented lines. Commented formats are listed in http://www.opengl.org/wiki/GLAPI/glTexStorage2D but looks like not using in osg." Note from Robert Osfield. Changed the env var control to OSG_GL_TEXTURE_STORAGE and made it's value true by default when the feature is supported by the OpenGL driver. To disable to use of glTexStorage2D use OSG_GL_TEXTURE_STORAGE="OFF" or "DISABLE" git-svn-id: http://svn.openscenegraph.org/osg/OpenSceneGraph/trunk@14275 16af8721-9629-0410-8352-f15c8da7e697
