* Revision 2.83 2005/01/28 04:05:05 phreak
* shockwave weapons now work properly with the electronics (d-missible) tag
* added in a "randomness factor" for electronics parameters. This adds or subtracts
* a random value between 0 and this factor to the disruption time. This was hard coded
* to be 4 seconds in retail.
*
* Revision 2.82 2005/01/11 04:05:23 taylor

*
* Revision 2.66 2004/06/22 23:14:10 wmcoolmon
* Nonworking OGG support for sound (not music) added, disabled load-only-used-weapons code, modification to sound system registry code.

* Please note that from now on OGL will only run with a registry set by Launcher v4. See forum for details.
* OK, these changes effect a lot of file, I suggest everyone updates ASAP:
* Removal of many files from project.
* Removal of meanless Gr_bitmap_poly variable.
* Removal of glide, directdraw, software modules all links to them, and all code specific to those paths.
* Removal of redundant Fred paths that arent needed for Fred OGL.
* Have seriously tidied the graphics initialisation code and added generic non standard mode functionality.
* Fixed many D3D non standard mode bugs and brought OGL up to the same level.
* Removed texture section support for D3D8, voodoo 2 and 3 cards will no longer run under fs2_open in D3D, same goes for any card with a maximum texture size less than 1024.

* Revision 2.40 2003/09/26 14:37:16 bobboau
* commiting Hardware T&L code, everything is ifdefed out with the compile flag HTL
* still needs a lot of work, ubt the frame rates were getting with it are incredable
* the biggest problem it still has is a bad lightmanegment system, and the zbuffer
* doesn't work well with things still getting rendered useing the sofware pipeline, like thrusters,
* and weapons, I think these should be modifyed to be sent through hardware,
* it would be slightly faster and it would likely fix the problem
