Exactly, the GL_LIMITS is the problem. The gl info structure is stored in the
adapter, and the adapter is found via a pointer in the device. If there is no
gl there is no d3d adapter, ergo the pointer is NULL.
Making sure that GL_LIMITS does not crash but just returns 0 sounds tempting,
but I am afraid that this provokes more nasty issues. We should just watch
out not to call it without gl, and crashing if we do is a nice way to show us
that something is wrong.
