`glGetString(GL_VERSION)` will return NULL without a current context. Commitdabc7d8b(“xwayland: Fall back to GLES2 if we don't get at least GL 2.1 in glamor”) would check the context is created, but it is made current just after, so the call to `epoxy_gl_version()` would return 0, hence defeating the version check. Make the context current prior to call `epoxy_gl_version()`.
