// system and are quite opaque to use from the outside (see @ref ValidatePosition).

// our props and sets it on their respective models. In particular, @ref ValidatePosition will compute the prop's
// world-space transform as either
//
// T' = T x B x O

// T' = T x O

// where T' is the prop's world-space transform, T is our world-space transform, O is the prop's local
// offset/rotation matrix, and B is an optional transformation matrix of the bone the prop is attached to
// (taking into account animation and everything).

* Rendering approach:
*
* m->submissions contains the list of CModels to render.
*
* The data we need to render a model is:
* - CShaderTechnique
* - CTexture
* - CShaderUniforms
* - CModelDef (mesh data)
* - CModel (model instance data)
*
* For efficient rendering, we need to batch the draw calls to minimise state changes.
* (Uniform and texture changes are assumed to be cheaper than binding new mesh data,
* and shader changes are assumed to be most expensive.)
* First, group all models that share a technique to render them together.
* Within those groups, sub-group by CModelDef.
* Within those sub-groups, sub-sub-group by CTexture.
* Within those sub-sub-groups, sub-sub-sub-group by CShaderUniforms.
*
* Alpha-blended models have to be sorted by distance from camera,
* then we can batch as long as the order is preserved.
* Non-alpha-blended models can be arbitrarily reordered to maximise batching.
*
* For each model, the CShaderTechnique is derived from:
* - The current global 'context' defines
* - The CModel's material's defines
* - The CModel's material's shader effect name
*
* There are a smallish number of materials, and a smaller number of techniques.
*
* To minimise technique lookups, we first group models by material,
* in 'materialBuckets' (a hash table).
*
* For each material bucket we then look up the appropriate shader technique.
* If the technique requires sort-by-distance, the model is added to the
* 'sortByDistItems' list with its computed distance.
* Otherwise, the bucket's list of models is sorted by modeldef+texture+uniforms,
* then the technique and model list is added to 'techBuckets'.
*
* 'techBuckets' is then sorted by technique, to improve batching when multiple
* materials map onto the same technique.
*
* (Note that this isn't perfect batching: we don't sort across models in
* multiple buckets that share a technique. In practice that shouldn't reduce
* batching much (we rarely have one mesh used with multiple materials),
* and it saves on copying and lets us sort smaller lists.)
*
* Extra tech buckets are added for the sorted-by-distance models without reordering.
* Finally we render by looping over each tech bucket, then looping over the model
* list in each, rebinding the GL state whenever it changes.
