As we develop the partition algorithm, we need to store more information
per partition to describe the phase and other parameters.
To keep this data together, further abstract the existing v4l2_rect
into a partition specific structure
When generating the partition windows, operate directly on the partition
struct rather than copying and duplicating the processed data
