SDK 0.4.0 struct ovrDistortionVertex

The 'ovrDistortionVertex' struct in the SDK 0.4.0 does not match the documentation, and I have no clue what to do with this.

Either that, or I'm drunk.

This is the struct as in the SDK...

/// Describes a vertex used by the distortion mesh. This is intended to be converted into
/// the engine-specific format. Some fields may be unused based on the ovrDistortionCaps 
/// flags selected. TexG and TexB, for example, are not used if chromatic correction is 
/// not requested.
typedef struct ovrDistortionVertex_
{
    ovrVector2f ScreenPosNDC;    // [-1,+1],[-1,+1] over the entire framebuffer.
    float       TimeWarpFactor;  // Lerp factor between time-warp matrices. Can be encoded in Pos.z.
    float       VignetteFactor;  // Vignette fade factor. Can be encoded in Pos.w.
    ovrVector2f TanEyeAnglesR;
    ovrVector2f TanEyeAnglesG;
    ovrVector2f TanEyeAnglesB;    
} ovrDistortionVertex;

This is the example code...

DistortionVertex * v = pVBVerts;
ovrDistortionVertex * ov = meshData.pVertexData;
for ( unsigned vertNum = 0; vertNum < meshData.VertexCount; vertNum++ )
v->Pos.x = ov->Pos.x;
v->Pos.y = ov->Pos.y;
v->TexR = (*(Vector2f*)&ov->TexR);
v->TexG = (*(Vector2f*)&ov->TexG);
v->TexB = (*(Vector2f*)&ov->TexB);
v->Col.R = v->Col.G = v->Col.B = (OVR::UByte)( ov->VignetteFactor * 255.99f );
v->Col.A = (OVR::UByte)( ov->TimeWarpFactor * 255.99f );
v++;

Or did they just rename all the parameters?
