Hopefully work around an issue where older Intel drivers on Windows use Microsoft's OpenGL 1.1 software renderer instead of failing to create the context, when a requested framebuffer attribute value is unsupported.

Failing to create the context is preferred in that situation because love's code will then try disabling various framebuffer settings to get a hardware-accelerated context using a supported OpenGL version.
