* Halo z buffering ----------------------------------------------
|
|
*
|
|
* A halo is treated here as a billboard: no z-extension, always
|
|
* oriented perpendicular to the viewer. The rest of the z-buffer
|
|
* stores face-numbers first, then calculates colours as the
|
|
* final image is rendered. We'll use the same approach here,
|
|
* which differs from the original method (which was add halos per
|
|
* scan line). This means that the z-buffer now also needs to
|
|
* store info about what sort of 'thing' the index refers to.
|
|
*
|
|
* Halo extension:
|
|
* h.maxy ---------
|
|
* | h.xs + h.rad
|
|
* | h.xs
|
|
* | h.xs - h.rad
|
|
* h.miny ---------
|
|
*
|
|
* These coordinates must be clipped to picture size.
|
|
* I'm not quite certain about halo numbering.
|
|
*
|
|
* Halos and jittering -------------------------------------------
|
|
*
|
|
* Halos were not jittered previously. Now they are. I wonder
|
|
* whether this may have some adverse effects here.
|

|
* @return 1 for succes, 0 if the operation was interrupted.
