Functions
static void	R_TransformModelDirect (modelInfo_t *mi)
static void	R_DrawMeshModelShell (const mAliasMesh_t *mesh, const vec4_t color)
	Draws an animated, colored shell for the specified entity. Rather than re-lerping or re-scaling the entity, the currently bound vertex arrays are simply re-drawn using a small depth offset and varying texcoord delta.
static void	R_DrawAliasFrameLerp (mAliasModel_t mod, mAliasMesh_t mesh, float backlerp, int framenum, int oldframenum, const vec4_t shellColor)
	Animated model render function.
static void	R_DrawAliasStatic (const mAliasMesh_t *mesh, const vec4_t shellColor)
	Static model render function.
const float *	R_GetTagMatrix (const model_t mod, const char tagName)
	Searches the tag data for the given name.
void	R_ModelAutoScale (const vec2_t boxSize, modelInfo_t *mi, vec3_t scale, vec3_t center)
	Compute scale and center for a model info data structure.
void	R_DrawModelDirect (modelInfo_t mi, modelInfo_t pmi, const char *tagname)

static mAliasMesh_t* R_GetLevelOfDetailForModel	(	const vec3_t	origin,
		const mAliasModel_t *	mod
	)			`[static]`

Searches an appropriate level-of-detail mesh for the given model.

Parameters:

	origin	The origin the model should be placed to in the world
	mod	The model where we are searching an appropriate level-of-detail mesh for

Returns:: The mesh to render

const float* R_GetTagMatrix	(	const model_t *	mod,
		const char *	tagName
	)

Searches the tag data for the given name.

Parameters:

`[in]`	mod	The model to search the tag data. Can be `NULL`
`[in]`	tagName	The name of the tag to get the matrix for. Might not be `NULL`

Returns:: The tag matrix. In case the model has no tag data assigned, NULL is returned. The same is true if the given tag name was not found in the assigned tag data.

Note:

Matrix format:

0-11: rotation (forward, right, up)
12-14: translation
15:

void R_ModelAutoScale	(	const vec2_t	boxSize,
		modelInfo_t *	mi,
		vec3_t	scale,
		vec3_t	center
	)

Compute scale and center for a model info data structure.

Parameters:

`[in]`	boxSize	The size the model should fit into
`[in,out]`	mi	The model info that contains the model that should be scaled
`[out]`	scale	The scale vector
`[out]`	center	The center of the model (center of the model's bounding box)

Note:: The scale and center vectors are parameters here because the modelInfo_t struct only holds pointers to the vectors.

Todo:: Take the rotation info from modelInfo_t into account
