The DeviceInfo structure has many OpenGL and GLSL fields that will not be used for other non-OpenGL graphics API's.

It makes sense to split these into two separate structures GLInfo and GLSLInfo and then have:

type DeviceInfo struct {
    // GL is a pointer to information about the OpenGL implementation, if the
    // device is a OpenGL device. Otherwise it is nil.
    GL *GLInfo

    // GLSL is a pointer to information about the GLSL implementation, if the
    // device is a OpenGL device. Otherwise it is nil.
    GLSL *GLSLInfo
