Steps reproduce:
1. Open attached project
2. Open ShadowMeta.cginc
3. Replace UnityObjectToClipPos(pos4) to mul(UNITY_MATRIX_MVP, pos4)
4. Save script
5. Notice that mul(UNITY_MATRIX_MVP, pos4) is upgraded to UnityObjectToClipPos(pos4)

Expected result: mul(UNITY_MATRIX_MVP, pos4) should not be replaced with UnityObjectToClipPos(pos4)

    Is working:
    float4x4 vp = mul(UNITY_MATRIX_MVP, unity_WorldToObject);

    Forced by Unity replaced by
    float4x4 vp = UnityObjectToClipPos(unity_WorldToObject);

    This generates an error: Shader error in 'custom/Billboard': 'UnityObjectToClipPos': cannot implicitly convert from 'float4x4' to 'float4' at line 132 (on d3d11)

    Shaders now are broken, and no way to fix them. Please take in account 4x4 case.

    In version 2017.1.0b1

    Breaks a shader called GizmoShader

    Lines fail ZTest and are rendered over geometry

    I hope this is fixed before release

    The same for mul(UNITY_MATRIX_MVP, mat4x4)
    Hope this is fixed too.
