+Subject: [PATCH] Faker: Fix build issue w/ Mesa 19.3.0+ headers
+
+Mesa changed the signatures for glXGetTransparentIndexSUN() and
+glXQueryGLXPbufferSGIX() to match the official GLX extension specs:
+https://www.khronos.org/registry/OpenGL/extensions/SUN/GLX_SUN_get_transparent_index.txt
+https://www.khronos.org/registry/OpenGL/extensions/SGIX/GLX_SGIX_pbuffer.txt
+
+Reference:
+https://gitlab.freedesktop.org/mesa/mesa/commit/3dd299c3d5b88114894ec30d1fac85fba688201f
