| 5 : | ; This macro provides a assembler width/height scroll loop | ||
| 6 : | ; NAME function name | ||
| 7 : | ; STACK additional stack bytes required by FUNC | ||
| 8 : | ; BYTES bytes-per-pixel for the given colorspace | ||
| 9 : | ; PIXELS pixels (columns) operated on per FUNC call | ||
| 10 : | ; VPIXELS vpixels (rows) operated on per FUNC call | ||
| 11 : | ; FUNC conversion macro name; we expect to find FUNC_INIT and FUNC macros | ||
| 12 : | ; ARG1 argument passed to FUNC | ||
| 13 : | ; | ||
