Summary0015961: Single remote server brighter rendering remote server with Opacity.
DescriptionStrangly, PV is rendering images brighter remote server than single server with one remote server. This happens with Opacity.

* Linux, master,remote server - 1 server, rendering with software Mesa3d (OGL2).
* Edit/ Settings/ Render View/ Remote Render Threshold set to 0.
* (Image compression should be default, which is Squirt compression, level 3.)
* OK.
* Sources/ Wavelet. Apply. Surface. Color by RTData.
* Color Editor/ Eanble opacity mapping for surfaces.

Now, notice how bright the wavelet is. This is probably incorrect.
* Edit/ Settings/ Render View/ Remote Render Threshold set to 20.

Now, notice how dim the wavelet is. This is correct.

    BUG 0015961: Fix blending issues for remote rendered images.
    
    For the reported bug, the server-side background color gets blended into
    the renderered image. When the image is delivered to the client and then
    blended on to the image on the client side, we end up with the
    background color getting blended in again. This was causing the
    brightness issue reported. We address this bug by making server ranks
    render with a black background always (when in modes where remote
    rendered image is delivered to the client).
