xstep	Step between each column for selection in the xbuffer.
zbuff	Input buffer of 16 elements of type int16
zstart	Starting position offset applied to all lanes for input from Z buffer. This must be a compile time constant. Only the 4 LSB of the argument are used.
zoffsets	4b offset for each lane, applied to input from Z buffer. LSB apply to first lane
zstep	Step between each column for selection in the zbuffer.

• Parameter 'zstart' must be a compile time constant.
