support probing with image projection ?

[cxlcl]

Does this plugin support probing with spatially coded illumination ?

When I set the probing mode to epipolar, and set the pattern for the projected image to be stripe, I didn't get the projected pattern at all.

For example, when the probe mode is set to be epipolar with stripe projection, here is the image I got:

Below is the scene description
`

<integrator type="bdpt">

    <boolean name="sampleDirect" value="false"/>
