Wait, maybe it's referring to a specific product. For example, Adobe uses CR for Campaign Response, but that's a stretch. Or maybe it's related to OpenGL (Graphics Library), but "CR GL" would not make sense. Maybe Cross Reality (XR) technology, like CR for Cross-Reality, and GL as Graphics Library, so CRGL is a library for Cross-Reality graphics, and "thirdparty" refers to plugins or additional integrations.
