[Bf-cycles] Creating a sky environment programatically

[F Escobar]

The BSDF was just a desesperate try,

For future readers: my bad was not connecting bkNode to the graph!

A couple issues:
* bkNode is not added to the background shader graph.
* Don't add BSDF to the background shader, it makes no sense.
* Connect bkNode->output("Background") to graph->output()->input("Surface") directly.

I thought that this could be easy... but I was wrong

ccl::BackgroundNode* bkNode = new ccl::BackgroundNode();
ccl::Background* bk = scene->background;
ccl::Shader *shader = scene->default_background;
ccl::ShaderGraph *graph = shader->graph ;

ccl::SkyTextureNode* sky = new ccl::SkyTextureNode();
graph->add(sky);

ccl::DiffuseBsdfNode *diffuseBSDF = new ccl::DiffuseBsdfNode();
graph->add(diffuseBSDF);
graph->connect(sky->output("Color"), bkNode->input("Color"));
graph->connect(bkNode->output("Background"), diffuseBSDF->input("Color"));
graph->connect(diffuseBSDF->output("BSDF"), graph->output()->input("Surface"));

shader->tag_update(scene);
bk->tag_update(scene);

That looks fair on my head but I only get a black environment so that's wrong for sure.

Any Idea on this? I bet that is something related to update the bk or the bkNode.

Thank you in advance
