/// Generate distortion mesh per eye.
/// Distortion capabilities will depend on 'distortionCaps' flags. Users should
/// render using the appropriate shaders based on their settings.
/// Distortion mesh data will be allocated and written into the ovrDistortionMesh data structure,
/// which should be explicitly freed with ovrHmd_DestroyDistortionMesh.
/// Users should call ovrHmd_GetRenderScaleAndOffset to get uvScale and Offset values for rendering.
/// The function shouldn't fail unless theres is a configuration or memory error, in which case
/// ovrDistortionMesh values will be set to null.
/// This is the only function in the SDK reliant on eye relief, currently imported from profiles,
/// or overridden here.
