3D acceleration not working on OSE

[Robert Millan]

3D acceleration does not appear to be working on OSE. The checkbox is present, but marking it won't result in VBox.log including the usual information about OpenGL (e.g. "OpenGL Info: Render SPU: GL_VENDOR: blah").

I suspect it has something to do with incomplete handling of the OpenGLEnabled configuration setting. It is checked for, but there seems to be no code to enable it:

$ rgrep OpenGLEnabled src/ src/VBox/Main/VMMDevInterface.cpp: if (!CFGMR3AreValuesValid(pCfgHandle, "Object\0OpenGLEnabled\0crOpenGLEnabled\0")) src/VBox/Main/VMMDevInterface.cpp: rc = CFGMR3QueryBool(pCfgHandle, "OpenGLEnabled", &fEnabled);
