opencv: switch deprecated cvSmooth for GaussianBlur

Browse source 
The OpenCV cvSmooth function is deprecated [0] and the documentation
recommends to use GaussianBlur (). This makes the spatial property go
unused. Marking it as deprecated, making it non-functional and will remove
in the next cycle.
