Subject: [SDL] Bug in GL_SWAP_CONTROL extension name.
The checked extension name is incorrect.
The attached patch fixes it to the correct name.
I don't think that under any setup, this extension name was ever
correct, which is why its not OR'd against the old check.
This fixes the "tear effect" (vsync problems) I had here with nVidia
GLX drivers.
