high precision model software rendering

[Seth G. <sga...@li...>]

I have commited the code that renders high precison models in
software.  GL rendering should be easy, and fortunately my sister's car
broke down and I can't drive so I don't have to fix her computer tommorow
and can work on QF instead :-)

Also I want to remove the last vestiges of hard coded vertex limits from
sw_ralias.c and sw32_ralias.c.  In both cases it's these two temporary
arrays in R_AliasDrawModel.  In fact here's the whole function:

#define MAXALIASVERTS 1024
void
R_AliasDrawModel (alight_t *plighting)
{
	finalvert_t finalverts[MAXALIASVERTS +
		((CACHE_SIZE - 1) / sizeof (finalvert_t)) + 1];
	auxvert_t auxverts[MAXALIASVERTS];
	r_amodels_drawn++;
	// cache align
	pfinalverts = (finalvert_t *)
		(((long) &finalverts[0] + CACHE_SIZE - 1) & ~(CACHE_SIZE - 1));
	pauxverts = &auxverts[0];
	paliashdr = Cache_Get (&currententity->model->cache);
	pmdl = (mdl_t *) ((byte *) paliashdr + paliashdr->model);
	R_AliasSetupSkin ();
	R_AliasSetUpTransform (currententity->trivial_accept);
	R_AliasSetupLighting (plighting);
	R_AliasSetupFrame ();
	if (!currententity->colormap)
		Sys_Error ("R_AliasDrawModel: !currententity->colormap");
	acolormap = currententity->colormap;
	if (acolormap == &vid.colormap8 && r_pixbytes != 1)
	{
		if (r_pixbytes == 2)
			acolormap = vid.colormap16;
		else if (r_pixbytes == 4)
			acolormap = vid.colormap32;
		else
			Sys_Error("R_AliasDrawmodel: unsupported r_pixbytes %i\n",
				r_pixbytes);
	}
	if (currententity != r_view_model)
		ziscale = (float) 0x8000 *(float) 0x10000;
	else
		ziscale = (float) 0x8000 *(float) 0x10000 *3.0;
	if (currententity->trivial_accept && pmdl->ident != POLYHEADER16)
		R_AliasPrepareUnclippedPoints ();
	else
		R_AliasPreparePoints ();
	Cache_Release (&currententity->model->cache);
}

I'd like these arrays to be either dynamically sized or resized,
with no hardcoded limit.  What is the best way to do that?
