*
* C file that contains functions for drawing target brackets on the HUD

* $Log: not supported by cvs2svn $
* Revision 2.26 2005/09/25 08:25:15 Goober5000
* Okay, everything should now work again. :p Still have to do a little more with the asteroids.
* --Goober5000
*
* Revision 2.25 2005/09/25 05:13:06 Goober5000

* --Goober5000
*
* Revision 2.24 2005/07/25 05:24:16 Goober5000
* cleaned up some command line and mission flag stuff
* --Goober5000
*
* Revision 2.23 2005/07/18 03:44:01 taylor
* cleanup hudtargetbox rendering from that total hack job that had been done on it (fixes wireframe view as well)
* more non-standard res fixing
* - I think everything should default to resize now (much easier than having to figure that crap out)
* - new mouse_get_pos_unscaled() function to return 1024x768/640x480 relative values so we don't have to do it later
* - lots of little cleanups which fix several strange offset/size problems
* - fix gr_resize/unsize_screen_pos() so that it won't wrap on int (took too long to track this down)
*
* Revision 2.22 2005/06/22 15:17:53 taylor

*
* Revision 2.15 2005/02/18 09:54:41 wmcoolmon
