| 33 | * The following macros may be defined to indicate what auxillary information

| 34 | * must be interplated along the line:
|
|---|
| 35 | * INTERP_RGBA - if defined, interpolate RGBA values
|
|---|
| 36 | * INTERP_SPEC - if defined, interpolate specular RGB values
|
|---|
| 37 | * INTERP_INDEX - if defined, interpolate color index values
|
|---|
| 38 | * INTERP_STUV0 - if defined, interpolate unit 0 STU texcoords with
|
|---|
| 39 | * perspective correction
|
|---|
| 40 | * NOTE: OpenGL STRQ = Mesa STUV (R was taken for red)
|
|---|
| 41 | * INTERP_STUV1 - if defined, interpolate unit 1 STU texcoords
|
|---|
| 42 | *
|
|---|
| 43 | * Optionally, one may provide one-time setup code
|
|---|
| 44 | * SETUP_CODE - code which is to be executed once per line
|

| 45 | *
|

| 46 | * To actually "plot" each pixel the PLOT macro must be defined.

|

| 48 | * This code was designed for the origin to be in the lower-left corner.
