* clutter/cogl/gl/cogl-defines.h.in: * clutter/cogl/gl/cogl-context.h: * clutter/cogl/common/cogl-mesh.c: Rename the glBufferDataSub function to glBufferSubData. When calling glXGetProcAddress with the former Mesa returns a stub dispatch function which will segfault if you try to use it. With NVIDIA it returns NULL so _cogl_features_init decides the card doesn't have VBO support.
