* moved the binding commands to osd.cpp. They were in the global namespace already and this way everything to be tossed out is in the same place when the time comes.
* removed support for the OSDs native CVARs. The only ones left were some internal ones I won't need until this code can be replaced.
* same for the custpmization code the games added. Duke Nukem was the only one anyway to have a decent font for it.
Some part are not done yet, and the file system data is currently ignored - there's no way to properly set this up with the file system code Build came with.
This is a lot of changes in a lot of code because nothing here was abstracted into the sound system. :(
Hopefully most of the affected code here can be tossed out soon, it's not pretty.
This is going to be a lot of work consolidating the 3 frontends' settings but a necessary evil for eventually getting Shadow Warrior to work as it is quite lacking here.
In this case a different open function is used because this is normally files on the hard drive and not assets, so being able to have a different setup for finding them is important.
- consolidated Polymost precaching and removed precaching for static tiles because they now are always loaded.
- removed cache configurability. On modern systems this is relatively pointless - allocating 50 or 100 MB is a non-issue - and the cache is due for replacement anyway.
Sorry, but having a globally writable pointer to every texture is just insane and makes any functional management impossible.
This is merely a preparation for adding a real texture manager. That cannot be done if any code can write over the data at will. For that, it now has to make the texture writable first or create a writable empty texture.
- also removed the legacy fog modes because their implementation did not mix well with the texture system - they are also not really useful to begin with.
The last fog mode will most likely also be removed once true color shading is working but that one is less of an issue.
