remove two old/unused MR flags (MR_ALWAYS_REDRAW, used for caching that doesn't work; MR_SHOW_DAMAGE, didn't do anything)
add MR_FULL_DETAIL to render an object regardless of render/detail box setting
change "model_current_LOD" to a global "Interp_detail_level" and the static "Interp_detail_level" to "Interp_detail_level_locked", a bit more descriptive
minor bits of cleanup
change a couple of vm_vec_scale_add2() calls to just vm_vec_add2() calls in ship.cpp, since that was the final result anyway
* remove a bunch of old/dead code
* some reformatting to help with readability
* rearrange/rename some code so that it is a little clearer
* move thruster glow code to it's own function (model_render_thrusters())
make HTL model buffers dynamic
fix detail boxes so that they actually work for the first time
- use MR_AUTOCENTER and MR_IS_MISSILE flags to generate an autocenter for a missile if one doesn't already exist
- don't try to autocenter loadout icons when rendered 3d
- put glowmap activity back on a per-ship basis (via a SF2_* flag) rather than per-model
- same for glowpoints, back on a per-ship basis
- put specmaps and bumpmap back on a LOD0 and LOD1 affect (got changed to LOD0 only recently)
- fix glowmaps for shockwaves again
- add support for animated specmaps (mainly for TBP and Starfox mods)
some minor code cleanup and compiler warning fixes
minor cleanup of some modelinterp.cpp code, to make it more readable
fix tertiary thruster batcher which had the radius value swapped
comment out a couple places where we were doing a D3D or OGL check (it's always true so why bother)
add more support for NO_DIRECT3D so that it can be used on Windows to build without D3D
more bmpman related fixes, mainly addresses the condition where it would try to render textures that have been released
have model_unload() run through Ship_info[] and clear out modelnum's when they are free'd (makes more sense here than doing it on level load to keep counts right)
fix missing subsystem warning messages
let gr_render_buffer() render untextured polys (OGL only until some D3D people fix it on their side)
add MR_SHOW_OUTLINE_HTL flag so we easily render using HTL mode for wireframe views
make Interp_verts/Interp_norms/etc. dynamic and get rid of the extra htl_* versions
modelinterp.cpp:parse_tmap() -> first IS_VEC_NULL() check would fail, wasn't a second on reassign
aicode.cpp:ai_path() -> when (Pl_objp->pos == gcvp), fixed globally in vecmat.cpp:vm_vec_dot_to_point()
