* 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.

*
* 44 11/16/97 12:20p John
* added code to make ships instantly warp in/out if fireball effect

* to bm_load functions not needed. Made bmpman keep track of palettes
* for bitmaps not mapped into game palettes.
*
* 33 8/29/97 2:26p John
* first rev of ship warp in effect. Nothing more than a fireball inside
* of freespace, but textest.cpp contains the correct effect code that
* needs to be transferred into the game next.
*
* 32 8/21/97 5:11p Lawrance
* frame numbering for ANI's now is from 0 -> total_frames-1.
*
* 31 8/13/97 9:50p Allender
* split *_move into *_process_pre and *_process_post functions.
* process_pre functions called before object is moved. _process_post
