DEU 5.0 BETA4

There are no docs in this version, because people are working on them.
You can get the latest version of the documentation files on my ftp server:
bear.montefiore.ulg.ac.be (139.165.8.25).  I created a "docs" directory in
"/incoming/doom".  Note: The server is fast, but our Internet connection is
slow (64 Kbit/s) and heavily loaded.  Don't forget: this site is in Europe.

>>> The server may be down during this week-end: be sure to get the files
>>> before Friday evening...

Problems:
- Bug in the Nodes builder: sometimes (for instance, on E1M1) the Nodes
  builder will crash because of round-off errors when splitting a Seg in two.
  The program will report this error: "nodeline picked twice".  This is because
  a Seg has been split in two, but because of round-off error in the middle
  Vertex coordinates, it still thinks that one part the Seg should be split.
  In other words, it thinks that the new Vertex is not on the nodeline after
  the split, so this nodeline is choosen once again because it has Segs on
  both sides of it.  Maybe using a 8x8 grid will help?
- Most mouse drivers aren't VESA or SuperVGA-compatible.  If you use the higher
  resolutions, your cursor will be invisible (and useless!).  Upgrading your
  mouse driver should solve this problem.  If you have a public-domain (freely
  distributable) mouse driver that works with VESA or SuperVGA modes, please
  put it on my ftp server...

Warnings:
- You must have more than one Sector in your test levels.  If you try and build
  a level with only one Sector in it, the Nodes builder will crash with the
  following error: "nodeline not found".  Because you can't create a Nodes tree
  if there is only one convex polygon in the level.  If you find a way around
  this, please tell me, but I think that it's logically impossible.
- If you don't want to rebuild the Nodes, Reject and BlockMap each time you
  save a level, turn off the "Expert" mode...  You think you're a brain, now
  get those bugs...

New features:
- Major bug in the Nodes builder fixed!  Try it now!
- VESA support.  You can now edit your levels with various video modes:
  640x480x256, 800x600x256, 1024x768x256,...  If the BIOS of your video card
  is not VESA-compatible, you can try loading the UNIVESA TSR before lauching
  DEU.  The position of the menus, info box, etc. are resized according to the
  current video mode.  Trevor Phillip (RPHILLIP@cc.curtin.edu.au) gave me a
  generic SuperVGA driver, but this doesn't work for now (at least, not with my
  old TVGA8900 card).  You'll have to use the VESA driver until this is fixed.
- Thanks to Alistair Brown (A.D.Brown@bradford.ac.uk), I fixed a nasty bug in
  the Reject builder.  This bug trashed the BlockMap (the next object in the
  PWAD file).  Now you should be able to save your level and NOT go through the
  walls...
- New command-line options.  Try "DEU -HELP" if you want a list of available
  options.  You can also use these options in DEU.INI.
- The "C[reate]" command has been fixed.
- New features are under development.  I put two new menus under 'F9' and 'F10'
  (do you have a better idea for the keys?).  Most of this is not implemented,
  but you can take a look...

Now what?
- There still are some bugs in the program.  If you find one bug and have a
  fix for it, please tell me!
- Lots of features are yet unimplemented.  Please don't ask me when it will be
  done, etc.  I already spend a lot of time reading my mail...
- You can give this temporary version to anyone you wish.  I won't have the
  time to finish it until a few days...
- If you create new levels with DEU, you can upload them to my server.  If you
  put them on another server, it would be nice to say that you made them with
  DEU...

Have fun!
