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.

First problem was that IGUIElement::getNextElement wasn't passing includeInvisible and includeDisabled flags recursively, so anything deeper than one level could fail if an element was disabled/invisible in between while it was created.
Second problem was that setTabOrder(-1) did ignore disabled elements. So when any parent was disabled when elements were created they never got a tab order.

Not optimal, but making this real 32-bit is sadly a bit more work.
This way at lest meshes with mixed 16/32 bit buffers can weld the 16-bit ones.

Lazy access function - same as for all other members of S3DVertex (getPosition/getNormal/getTCoords).
Not sure why color was missing, maybe got added later?
Would probably be better to have a getS3DVertex function instead which would cover them all, but it's only some slow (but nice) helper function anyway.

Cameras can render even when they are not in the scenemanager or onAnimate didn't get called for example because they are their parent are invisible.
So let's be safe and add another call to updateAbsolutePosition(). Some cost, but usually we don't have that many rendering cameras, so shouldn't matter (if it ever matters I suppose we could override OnAnimate and add a flag if it _was_ animated since last render call. Maybe that's even useful in general for SceneNodes?).
Similar CSceneNodeAnimatorCameraFPS was using getAbsolutePosition which was only updated after animators, so it was one frame behind.
And documented ICameraSceneNode functions a bit. Especially updateMatrices is a bit of a confusing name unfortunately.

Sorry, didn't think it through. Seemed to work at first, but works only if sort() ended up creating the same sorting as is used then for search.
While often the case, this is obviously not guaranteed. And can't do sort per type easily (this works with flags which remember if sorting had been done).

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! :-)

It's to allow image loader to check for sane limits for image sizes.
Idea came from this patch from sfan5 for Minetest: dbd39120e7
Thought solution is a bit different.
Image loader checks not yet added (will come soon).
Also note that limit is to s32. While u32 might work mostly it will run into some troubles with color converter for now (which maybe could be changes). Also 2GB ought to be enough for anybody, right?

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).

I had somewhat rashly removed operator = in [r6280]
But since c++11 implicit defined copy assignment operator is deprecated when a user-declared destructor exists.
Still... alternative would be adding copy assignment operator but neither that nor the virtual destructor seem to be needed.
So rather removind destructor which seems to add an unnecessary virtual function table for it (seems to be just used like a POD throughout the code)

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.

color intitialization has some cost, but we initialized all other values already (vectors are always set to 0).
Don't think it's a good idea to have one value around which is random.
S3DVertex2TCoords(S3DVertex& o) to S3DVertex2TCoords(const S3DVertex& o) simply because it makes more sense
S3DVertexTangents(const S3DVertex& o) added because I'll need it later (and no idea why only S3DVertex2TCoords got one of those before).

CIndexBuffer::setType could end up casting a temporary u16 variable to u32& (reference!).
Probably never noticed as this tended to mostly works (guess next byte on stack often 0?).
To prevent this from happening again I modifed IIndexBuffer::push_back to work with copies instead of references.
While breaking the interface anyway I also deprecated pointer() which is just identical to getData() anyway.
I get the idea of staying similar to core::array interface, but it's just confusing (and not same due to lack of types anyway).
Also added a const version for getData()
On a side-note - same setType bug still in CVertexBuffer, but a bit harder to fix there. So will be an new patch.

Did some tests and the overhead speed cost on loading and rendering where both not really measurable even in a pretty huge scene.
While some Irrlicht parts might still have a problem with 32-bit meshes (octree for example, also some meshmanipulator functions), it's probably still less of a problem than having broken meshes and just a nicer default. Also the troubling parts in Irrlicht can be improved over time.

Giving the loader it's own enum allowed me to add more options.
EITH_OPTIMAL which reduces buffers back to 16-bit if they don't need 32-bit.
Using that in obj loader.
Also 32-bit meshes with EMT_PARALLAX_MAP_SOLID material should now work in obj loader (untested as I got no test-case)

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.

1 Meshbuffer with 24 vertices, so each side has it's own vertices.
Normals perpendicular to the cube-sides.
CubeSceneNode accepts now a ECUBE_MESH_TYPE
CubeSceneNode::clone now also clones rotation and scale (not sure why it didn't do that before - hope there was no reason, but can't think of any).
ISceneManager::addCubeSceneNode accepts now a ECUBE_MESH_TYPE and passes it through.

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).

It's identical to the implicit one generated, so we don't need that.
And it triggers warnings with -Wdeprecated in newer gcc.
It's because the implicit definition of a copy constructor is deprecated if the class has a user-declared copy assignment operator.
There's a few more warnings about that in Irrlicht, will have to check them in detail as the other cases are not as trivial to fix as this one.

C++ has undefined behavior for identifiers starting with __ or with _ followed by an uppercase letter.
We still have many more (in IrrCompileConfig.h and in all header-guards), will likely replace those later as well.
As a workaround for users which might use irrlicht defines in their code, I've added the header irrLegacyDefines.h
Including that allows to continue using old defines for a while - or make it easier to have code which compiles
with old and new Irrlicht library versions.

New default is that the system decides itself.
Reason is that X11 didn't like the last change (disabling it on start) too much and we got messed up title-bars.
Or at least on some Window Managers. Which makes sense as X11 really requires Windows to be resizable in Windowed mode.

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.

It's never really done much in c++, was deprecated in c++11 and is reserved since c++17.
Thanks @Maksym Hamarnyk for remdinding me about this.
Note: there are few more register commands in third library .c code. It's still a valid keyword there.

This changes the behaviour on Win32 somewhat when Windows returned a CURSOR_SUPPRESSED state (touch-screen input hiding cursor globally).
Previously we set IsVisible it to false when CURSOR_SUPPRESSED was set.
Also we handle the CURSOR_SUPPRESSED state slightly different now and still try to hide cursors once when requested.
Reason for the change is that the old behaviour made it harder to recover from touch-screens hiding the cursor because Irrlicht didn't
know anymore which state is _should_ have. This also unifies the behaviour on all drivers as the other drivers already returned the visible
flag independent of the system being able to actually show the cursor.

UI and scenenodes are often connected. And while it was possible to work around this already by using custom draw functions
or deriving from gui and scene-nodes at the same time, it did already lead a few times to uglier code for me.
So I guess adding one more pass to the engine has it's uses.

Unlikely we ever support conversions with compressed image format.
Define is a bit ugly I guess, but nicest way I could think off.
Can probably be used in some image writers as well, have to check which support/don't support compressed formats first.

The f32 version jumped around more on gcc/linux (didn't do so with VisualStudio, mabye sqrt on VS already uses double internally).
