+Subject: [PATCH] c: Try loading OpenGL through EGL if GLX isn't available
+
+On a UNIX system without X11 libraries, it's impossible to have libGL.so
+and glXGetProcAddressARB(). Currently GLAD would fail to load GL symbols
+in this case.
+
+Try also loading libEGL.so/libEGL.so.1 in OpenGL loader and fallback to
+eglGetProcAddress() to query GL symbols if glXGetProcAddressARB() isn't
+available.
+
+Since EGL version 1.5 released in 2014, it's required for
+eglGetProcAddress() to be able to query all client API functions instead
+of only extensions, which is quite early for a Wayland-only display
+stack, thus no function check or another fallback logic is added.
