Running on an old intel graphics chip, should print a little error message along the lines of "need opengl2.1 support to run" before segfaulting.

related to: #1283 ?

If this still valid in the current master branch? If yes, a check for the OpenGL version should probably be added to provide a meaningful error message and close Godot without segfaulting.

Unfortunately I no longer have the hardware that was causing the problems in my possession.

Related to #1162.

Closing as a "won't fix" bug as there is nothing we can do to fix this issue. On the other hand #1162 proposes to catch the error before a segfault and to display a friendly error message, which should make this kind of errors easier to understand for the user.
