Implementation Notes:
---------------------
Baking for Cycles was implemented in two fronts:

In Blender we created a new operator that will try to bake using the current engine.
So far only Cycles has this implemented, but other engines (even the Blender Internal) could go through this API/pipeline.
The operator is responsible for the image handling, normal space
transformation, populate the UVs, loop over faces, ...

In Cycles we extended the baking functionality available for environment
and displacement for the other render passes (not all of them since some
of them doesn't make sense for baking).

The API is simple. Blender send a populated array of BakePixels to the
renderer, and gets back an array of floats with the result.

BakePixel is tjhe following struct:

struct BakePixel {
int primitive_id;
float u, v;
float dudx, dudy;
float dvdx, dvdy;
};
