This patch implements the variable size blur option in the Bokeh Blur node. The implementation is different from the CPU one in that it also takes the Bounding Box input into account, which is ignored for some reason for the CPU. Additionally, this implementation does not do the optimization where the search radius is limited relative to the maximum value in the size texture. That's because the cost of computing the maximum is not worth it for most use cases. The reference implementation does three unexpected things that are replicated here nonetheless. First, the center bokeh weight is always ignored and assumed to be 1. Second the size of the center pixel is taken into account. Third, a unidimensional distance is used instead of a 2D euclidean one. Those need to be considered independently.
