Rename to hline_zbuff and change number of user slave registers from 4 to 8 (didn't bother to read HLine prototype beforehand...)
Remove devl files.
Added zbuff write and byte enable fifos to hline_zbuff.
Wrote pseudocode for z interpolation operation along x's. May change algorithm, so not writing just yet.
