#687 Texture not rendered correctly

[Michael Bäuerle]

A texture (AUR008) is not rendered correctly in Pagodia:
https://www.doomworld.com/idgames/levels/doom2/p-r/pagodia
How to reproduce:
$ doomlegacy -iwad doom2.wad -file pagodia.wad -nomonsters -warp 6
At the starting point: Turn around and look at the middle texture of the gate.

Tested with Doom Legacy 1.48.12 (on NetBSD/amd64 with software renderer).
For comparison: Works with Crispy Doom 5.12.0.

It is amazing that Doomlegacy went so long without this bug being obvious.
I think it was correct about 2 years ago, but later bug fixes took out the correct code because it was not obvious what it was protecting against.

Fix to Bug 687.
In Pagodia.wad, Map06, the hanging vine texture had visual artifacts.
(AUR008, texture #624, lump 132961).
Due to some of the columns being totally empty, some
of the columns of the generated texture had the 0xFF termination,
in the wrong place.

Tested again with SVN 1647: Looks good now.
Ticket can be closed.
