* Change the order of operations such that linkdraw sprites aren't ever used for ordering comparisons with non-linkdraw sprites.
* Refactor of the unbundling to not involve modifying the next/prev links. * Make the booleans in vissprite_t use flags stored in sprite->cut instead. * Make the linkdrawn sprites much more linked - ie, same brightness (unless independently fullbright), same colormap, and don't draw if the tracer isn't being drawn. * Other minor corrections.
