So far SceneManager always sorted Nodes per render stage.
Now we allow sorting per mesh-buffer per render stage by creating a new node for each mesh-buffer.
It's only supported for CMeshSceneNode so far.
This allows to enable better transparency sorting for meshes which have transparent buffers.
Previously those always got rendered in the order in which they got added and ignored mesh-buffer bounding-boxes, but just used the bbox of the full mesh. Now they can use the bbox for each meshbuffer which can sometimes avoid render errors.
Also depending on the scene this can be quite a bit faster because it can help reduce texture changes. We sort solid nodes per texture, but only per node. So nodes with several textures had a texture switch between rendering each meshbuffer. And those are rather expensive in Irrlicht right now (and we support no bindless textures yet...)
Lastly it's now also used to buffer the render-stage. Checking this twice (once in registering the node and once in render) constantly showed up in the profiler. Which was a bit surprising really, but anyway - now it's gone.
I tried to keep it working for all cases we had before (all kind of situations, like when people may want to call render() outside the SceneManager). But not (yet) supporting the case of changing the meshbuffers (adding or removing some) without calling setMesh() again. Reason is that this wasn't well supported before either (node materials never updated). So for now I just assume people will call setMesh() again when they change the mesh.

New AbsPosUpdateBehavior which makes updateAbsolutePosition calls behave as if a node had no parent.
Allows for micro optimizations in cases where we have non-moving root node (all scenenodes are always added to the SceneManager which is generally not moved but it's transformation is still multiplied each frame for each node)
As a side-effect this also allows abusing the SceneManager to group objects without affecting transformations.
No real extra cost since I added ESNUA_TRANSFORM_POSITION already.
Thought turns out those matrix transformations are so fast that I also didn't noticed any difference in tests with > 20.000 nodes.

But at least some improvement.

Shouldn't have been removed with last commit.
But adding some comments as it's slightly confusing.

This makes it possible to set high-level shader constants (which are attached to shader programs) to be set outside
of OnSetConstants.
IShaderConstantSetCallBack::OnCreate has it set automatically now so it works the same as OnSetConstants.
D3D9 and burnings both work different, so there hadn't been a problem with those.

Accessing IMaterialRendererServices outside of OnSetConstants can be useful and Irrlicht made this a bit too hard to access.
Also OnCreate allows actually for nicer code where initialization and update of shader constants are strictly separated (see changed example).

Basically now the same as GLSL material renderer already worked.
Before it was using IMaterialRendererServices from CD3D9Driver, but there had been several problems with that:
- The d3d9 driver called functions through the CD3D9MaterialRenderer interface, but CD3D9HLSLMaterialRenderer is not (or maybe no longer?) derived from that class. Reason it still worked was accidental luck - the same functions had been in the same order and due to casts the compiler wasn't noticing it was calling the functions of an unrelated class.
- It was making calls to set shader constants depend on the currently set material in the driver. Which was not necessary and just prevents we can use the IMaterialRendererServices interface without setting the material first (how I found the bug).
Still some problems left for now:
- There's 2 ways to call shader constants. One seems to be only used by hi-level shaders which links constants to the shader. The the other only by low-level shaders which uses global (shader independent) registers.
So maybe this should be 2 interfaces? But not certain, glsl material renderer seems to prevent setting the global registers, but maybe those could be used additionally? I've still allowed it for now in HLSL, just in case it had it's uses.
- setBasicRenderStates probably should not be in IMaterialRendererServices. I'm not seeing any case where this isn't just passed on to the driver. And all classes using it have access to the driver unless I missed one. So probably can just avoid that additional indirection and kick that out of the IMaterialRendererServices interface.

This also fixes the combobox which users the listbox like that.
This got broken in [r6454] which had fixed the events send out by the listbox
Note: Still a bit strange behaviour when leaving the combobox at the bottom, but that was already that way in Irrlicht 1.8, so I've got to investigate that on it's own.

We had changed that once before in the other direction in svn r421
Reason back then was "Sleep(0) doesn't allow any lower priority threads to execute"
But Microsoft changed the behaviour of Sleep(0) after Windows XP so that's no longer true.
And the costs of it is pretty high - due to this using a timer with a 15ms resolutions it meant not just giving up the thread but it also always waited for 15ms on Windows.
I also replaced a few sleep calls in examples for that reason with yield() calls.

Pretty new internal (protected) variable, so renaming shouldn't break yet too much.
Reason is that VS code completion often showed that variable as first option before the way more used updateAbsolutePosition function. Which was a bit annoying.

Not quite sure why it was done that way. Maybe to ensure we work with byte-pointers of correct size or something?
Anyway, this doesn't seem to be defined in c++, so let's try working with a cast instead.
Just something cppcheck tool complained about.

Bitfields for PolygonOffsetDirection, ZWriteEnable and BlendOperation were chosen too small.
As we have pre c++11 code and therefore didn't use unsigned qualifiers for enums they were generally signed (up to compiler in theory, but I think they all choose signed).
Which means the bitfield also had a sign.
So for example setting PolygonOffsetDirection to EPO_FRONT set it to -1 instead of 1.
Which then would fail with comparison checks (PolygonOffsetDirection == EPO_FRONT would be false).
We kind of got lucky that we usually not checked for the last enum inside Irrlicht, so it worked to due being the "else" case.
Or in the ZWriteEnable case the last one was identical to the default return value so it also worked accidentally.
But obviously still wrong and user code could be messed up.
While at it I also re-ordered SMaterial variable so most bitfield variables are close together again to give compiler at least a chance to use packing. Thought at least in my quick debug compile test it didn't seem to use any packing (but maybe on other compilers).

- Only the getRotationDegrees without parameter is allowed to try fixing scale.
My fault when I added a new function which takes scale parameter, that one is
not allowed to be changed.
On the up-side - we know have for the first time an option which works in cases only
scale and rotation had been used and the user still has the correct scale.
Before any solution for that was broken
- getRotationDegrees fixes 2 places which caused wrong results due to floating point inaccuracies
New test for that got added
- Document the current restrains and problems of getRotationDegrees and getScale some more.
- Improve docs for other matrix4 functions.
- Add some comments about further improvements (I'll try if I find time)
Note: Irrlicht still assumes in at least 2 places (getting bone animations and Collada loader) that matrix
decomposing works. Which it doesn't yet for matrices which switch handedness (or have further transformations like skewing axes)
The bone animation is mostly fine for now with recent workaround (but that might cause other problems as it may be used too often), haven't checked Collada yet in detail.
TL/DR: This improves things with getRotationDegrees, but does not yet fix all troubles.

This is based on bugreport #458 reported by viwrap who also made a nice test-case model.
Note: While solution seems to work and would even be faster, I'm not 100% sure yet if there are no downsides.
The other solution seems to regard last column in matrices - thought I don't think we ever set or use that.
And I also haven't found out yet _why_ the original solution goes wrong.
But animation system uses right-hand quaternions unlike rest of Irrlicht which is obviously a bit dangerous, will have to check the conversions some day.

ISceneNode::setUpdateAbsolutePosBehavior can now control what ISceneNode::updateAbsolutePosition really does.
Having only the position and not the rotation/scale of a child node affected by the parent transformation was previously impossible inside the scene-graph. So people always had to break the scene-graph and code it themselves.
Old behaviour is default.
Extra check for new variable has a small cost, thought new behaviour can actually be faster when it's used.

It still won't work yet for scaled boundingboxes (or parents being scaled).
But at least it's now large enough for typical unscaled boundingboxes.
Before it was always too small - even for the simplest quadratic billboard case seen without rotation.
Now it's always a bit too large, but that's way less of a problem (collisions still work and culling simply happens a bit less often, but not too often which is way worse)

Was going wrong when setValue was called inside an event function for EGET_SPINBOX_CHANGED.
But last solution was overly complicated anyway as I tried too hard to avoid extra getValue calculations.
But noticing now those calculations got done anyway in all places where the event is triggered.
