S3DVertexTangents also documents that it's passed as TEXCOORD1 and TEXCOORD2, but easy to miss, so added some comments to the hlsl shader.
Also not all materials work well as base materials.

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.

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.

Previously search functions only worked when called with the same type as the array elements had.
Which forced users sometimes to create dummy objects to be able to search for elements by another type.
linear_search and linear_reverse_search now work with any type for which <T>::operator== is implemented.
Similar binary_search now works when <T>::operator< is implemented in both directions (T < E and E < T).
Note: It might be possible to further improve binary_search so only one operator< is needed (I think STL managed that somehow).
So if someone likes a challenge - have a go at it! :-)

Nothing good could come out of putting negative values into any of those functions.
And they are used a lot in image loaders which often can be tricked into passing large enough values to make those functions be called with negative numbers.

It's not 100% identical to what we had as I only copied up to MATERIAL_MAX_TEXTURES_USED before, but I think that was rather premature optimiziation.
(the cost for the extra textures is really in other places, don't think the copy here ever matters).
Was a bit based on Mintest patch, but they messed it up: 4931b34625
(because they didn't notice the difference between MATERIAL_MAX_TEXTURES_USED and MATERIAL_MAX_TEXTURES).

Previously vertex buffer did some invalid casts to references which could cause it to copy whatever was in memory into the vertex-arrays.
Generally it worked up to S3DVertex - but switch from another type to S3DVertex2TCoords or S3DVertexTangents caused it to be filled with whatever was in memory behind it.
Setter functions in IVertexBuffer have now overloads for all known vertex types.
Also adding const version of IVertexBuffer::getData.
And some warnings in comments about using the array functions (if even we mess it up...)
Also de-deprecate IIndexBuffer::pointer() again. I don't like having 2 functions for same stuff, but in the end it doesn't really hurt keeping it around.

Thanks @sfan5 for patch for Mintest: 4931b34625

Note - patch is not applied exaclty yet. SMaterial and matrix4 still missing (might be applied later).
Also patch was based on older Irrlicht and we removed a few already earlier this year (around r6280).

CMeshManipulator::createMeshCopy creates new meshes which have copies of the actual meshbuffers instead of copying everything into SMeshBuffers (which didn't support 32 bit or any of the other special features).

- IMeshLoader::setPreferredIndexType and getPreferredIndexType allow setting hints for the loaders if users prefer 16 or 32 bit meshbuffers. Loaders are free to ignore those hints (all but .obj will do that for now).
- obj meshloader loads now 32-bit buffers when setPreferredIndexType is set to EIT_32BIT.
NOTE: It's 16 bit meshes use now also an IDynamicMeshbuffer instead of an SMeshBuffer.
That will break the code of people who accessed meshbuffer before by casting to SMeshBuffer*
And might even be somewhat slower (lot's of virtual functions...), but shouldn't really matter and can maybe be a bit improved.
Sorry about that, I considered keeping SMeshBuffer for 16-bit (still considering it), but it would add some overhead in code and I don't think it's worth that. If there are any complains I'll maybe consider it again.

That was a bad case of premature optimization.
Multiplication is indeed faster, but when working with floats this can introduce some rather unexpected inaccuracies.
Like x/x suddenly no longer being 1.0 (something guaranteed by division).
If someone really needs this back, then please add some new function which makes it clear we don't just have a typical division here.

That makes it easier to use partial screens, while using automatic alignment.
Default is still automatic resizing as before, thought it got changed a bit as it looked a bit strange.
Before it only set the lower-right corner, but compared to driver screensizes, so it behaved a bit strange
when the leftTop corner of the rootGuiElement was changed (different than when the rightBottom corner was set).
Could be the idea before was that only clipping matters.

The way this was implemented BlendFactor and MaterialTypeParam could conflict otherwise as they both send the blend functions.
We could probably rewrite all places which use EMT_ONETEXTURE_BLEND+MaterialTypeParam to additionally check for BlendFactor, but it would still set the blend-functions twice.
I'm not sure if BlendFactor works with 2D materials currently? (but we can't set those to shaders yet anyway except in the gles branch...).
I've also started documenting a few things about how I suppose it's working, I hope I got it all right.

Fix bug that AnimatedMeshSceneNode ignored ReadOnlyMaterials flag when checking materials for transparent render passes.
Make IVideoDriver::getMaterialRenderer const.
Fix bugs in COctreeSceneNode, CMeshSceneNode and CAnimatedMeshSceneNode where check for transparency in OnRegisterSceneNode() and in render() where no longer identical (those got added after Irrlicht 1.8).
Some notes for future:
- Maybe we should have a getRenderPass instead of just needsTransparentRenderPass, but this way the code didn't need so much changes and behaves (aside from fixes) pretty much as before.
- Still wondering if the default implementation in CNullDriver::needsTransparentRenderPass should always return false when SMaterial.ZWriteEnable is set to EZW_ON.
This might be nicer with another material flag. Thought then we might want a material enum to choose the renderpass and that's more work.
And we get some recursion as needsTransparentRenderPass might want to check result of getWriteZBuffer which calls needsTransparentRenderPass, so we might need a second function or an additional flag there.
But return false when SMaterial.ZWriteEnable == EZW_ON could still be done as EZW_ON is a new flag so existing behavior shouldn't break. I just don't know right now if having an extra render pass for transparent nodes might still make sense even when zbuffer is not written or if that's really the only reason to do that. Any feedback anyone?

This breaks compiling. To have old values replace false with EZW_OFF and true with EWZ_AUTO.
There's a bit history to this change. ZWriteFineControl got introduced after 1.8 so it was never in a released version.
Basically it was needed after some changes had been made to allow shaders to have zwrite enabled independent
of the material-type (which worked badly for shaders). This had caused other problems as it was then enabled too often instead.
So to quickly fix those bugs and avoid breaking compatibility I had introduced a new enum ZWriteFineControl in SMaterial.
This worked and didn't break compiling - but I noticed by now that introducing a second flag for this made maintainance for an already
very hard to understand problem (figuring out the implementation of transparency and zwriting) even more complicated.
So to keep maintance somewhat sane I decided to break compiling now and merge those two flags.
The behavior should not be affected by this commit - except for users which set this flag already in their code and have to switch to the enum now.
Serialization is switched on loading old files (so SMaterial has enum already and writes that out).

Before OpenGL used GL_SPHERE_MAP instead of GL_REFLECTION_MAP in COpenGLMaterialRenderer.
Not sure why, but documentation mentioned GL not being implemented, so maybe it was forgotten?
Or maybe I'm missing something as this was a big too easy to fix :-)
Anyway - I tested it and with that change they seem to look now identical to the D3D9 version, so I think it's fine.
Obviously means whoever used the material before on OpenGL has now a changed material.
