b10141887f obj/mtl loader no longer messes up bump textures when the name starts with a number
Mtl loader was assuming bump textures starting with a number are always using that to scale the bump.
No idea if there are mtl files out there assuming that, but usually scaling parameter is -bm
But it always assumed real filename was following, so as compromise I still allow pure numbers (no other characters following) to be scaling parameters.

Also mtl file can now handle map_Bump on top of map_bump and bump (NASA model assets use that sometimes)

b17fe835bc Hardware meshbuffers are now deleted when they hold the last reference to a meshbuffer
HW buffers were keeping meshbuffers alive for 20000 frames even when no one else was using them anymore.
In cases of rapid creating/destroying static meshbuffers this could lead to serious memory leaks (which then kinda topped out after 5 minutes, but at that point it could already be too late).

989e82d5dd Initialize SJoint.Animatedscale to 1,1,1
No scale should be 1,1,1 not 0,0,0
Wasn't a bug as animation system ensured the initial value is never used, but more correct and no extra cost (vectors initialize to 0 otherwise).

56db5a39ea Deprecated and disable MY3D loader
I tried to find out about this format, but last info seems to be from 2005 (https://irrlicht.sourceforge.io/forum/viewtopic.php?p=37385)
Website for it no longer exists and I also couldn't find My3DTools on any other place on the web.
We don't even have an example for it in Irrlicht.
Also CMY3DHelper.h introduces quite a bunch of functions and global variables in the irr::core namespace and I'm not really interested in spending time in cleaning this up.

1d3794c8b4 Reduce redundant code in core::quaternion
Instead of using same matrix calculations 3 times, getMatrixCenter and getMatrix now both call getMatrixFast.
Additional function call might be slight cost in debug, in release compilers hopefully inline it away.
Also getMatrix_transposed now split into getMatrix_transposed and getMatrixFast_transposed to make it similar to getMatrix.
This also avoids a bunch of level 4 warnings in VS about function variables hiding class variables, which was why I started on this. Thought I also prefer having less code here.

6b2a0fab78 Fix tessellation numbers in createCylinderMesh, createConeMesh, createArrowMesh
Double tessellation numbers for these 3 functions in your code to get same results as in Irrlicht 1.8

I noticed in last commit those all tessellated semi-circles instead of circles. I just documented it there, but it's annoying as that bug doesn't allow odd numbered tessellation. So for example one couldn't create a triangle pyramid. 
I considered adding another parameter to describe what this number means, but... just too ugly. And it was always documented otherwise, so this could be considered a bug. Sorry if this changes the look of existing apps.

Also cleaned up code in CGeometryCreator::createCylinderMesh. No idea what the idea behind old code was. Aside from creating twice the tessellation numbers.

Thanks @randomMesh for reporting that they were missing: https://irrlicht.sourceforge.io/forum/viewtopic.php?p=307308
Also simplified that code a bit (same could probably also be done for createCylinderMesh, but too lazy right now)
Changed also UV's for top/bottom center vertex in CGeometryCreator::createCylinderMesh to use center for X (slight improvement, but would have to copy vertices to make it better)

8372a70f21 Fix uninitialized variable in CTriangleSelector and code cleanup
CTriangleSelector constructor with IAnimatedMeshSceneNode parameter didn't initialize MeshBuffer.
Not used internally, so no big problem, but it got passed back to users in some cases
Replaced SCollisionTriangleRange, by CTriangleSelector::SBufferTriangleRange. Was a bad idea to use a struct which is for something else just because some member were the same (my fault, sorry).
Also started unifying the case of using ranges vs not using them. 
Can maybe even get rid of the non-ranges case in future. Or unify the duplicated code for getting triangles at least.

66d189ce63 Bugfix: CTriangleSelector::getTriangles with bbox no longer ignores transform matrix
So far it only used the inverse of the node transformation to calculate the box used to check
Which gave wrong results as soon as one tried to pass an additional matrix transformation
Wasn't ever used internally or by examples in Irrlicht, so I guess no one ever noticed (also in some cases this still worked accidentally).

c9e71e26f2 Switch default transparency sorting back from ETNS_PLANE_CENTER to ETNS_CENTER
While there are some cases this fixes, like MartinVee's nice example for orthographic camera at https://irrlicht.sourceforge.io/forum/viewtopic.php?t=51598
it seemed to cause more problems in complex 3d scenes with perspective cameras.
Well anyway - both options are available now for those which need it.

3752bd9bd4 Add more transparent node sorting algorithms
Adding 2 algorithms to sort by distance to camera plane instead of camera position.
This is better in quite a few situations and extra cost is just one vector subtraction per node and an additional function parameter per call, I think that's worth it. So made the camera-plane to object-center now the new default.

3c4ac201ce Add options for transparency node sorting algorithm
Until last summer we sorted by object origin to camera distance
Since then we used nearest transformed bbox-extent to camera.
I've now added an enum to allow switching those plus 2 new:
- none (so sorting based on scenegraph instead)
- object center to camera. Which I made the new default as it worked the best in my tests.

I already experimented with a few more ones like different sphere sizes (bbox radius, minimal inbound radius, maximal inbound radius) around center or origin to handle objects with different sizes, but that just gave worse results for all my test cases.

Likely algorithms we should still try:
- Collision point with bounding-box in line between camera and object center (sounds a bit slow, but maybe worth it)
- Distance to camera plane (instead of camera position). But needs additional parameter to distance functions first (maybe normalized view vector will do). That should be useful when working with planar objects.

8bf9cf5471 writeImageToFile param now used by CImageWriterPNG for compression level
A bit annoying that it kinda has the opposite meaning for png and jpg compression for same parameter (png compression goes up, jpg goes down).
Also unfortunate we chose u32 instead of int here or we could at least use the usual zlib value range for png.
But I think it still won't mess up in many cases. Defaults (value 0) stay the same as before.
And setting a jpg range <= 10 is rarely done and even if so it just changes png sizes a bit now if people use writer for both. 
People just have to be careful now when they override defaults for png and then also write jpg - but can't help it.
And it's too  useful to not have this - this can massively change the write-speed for png's (like up to 3 times faster with no compression on my system).

feaed624f7 Remove serialization again from IUserData
This can't work as on deserialize it would need to have the type for IUserData already.
And that's impossible with the way it's used right now.
Would need some kind of factory or so probably, but I'll ignore this for now.
Note that it's still possible to call some serialization manually on the derived classes by adding it there if needed.

3c9a856e6d Add SMaterial::IUserData to make it easier passing additional values to shaders
Irrlicht generally avoided user pointers in the past, but after trying all kind of ugly workarounds - this is just easier and
not that much downsides really. Tiny speed costs due to additional SMaterial memory size and new comparison tests. 
But allows to keep SMaterial alive and useful for a while longer without needing a complete rewrite and it can now be used for stuff like writing PBR shaders.
Using a new interface io::IUserData for this which also allows serialization the user data (that part is untested so far, sorry)

d4f6d8c17b Add lens shift support for the camera and the perspective projection functions
As Blender docs describe it so nicely: Using lens shift is equivalent to rendering an image with a larger FOV and cropping it off-center.
This can be quite useful for architecture renderings, but I guess also has it's use in other situations.
Note: Didn't make the ICameraSceneNode functions pure virtual so users don't have to update their cameras for this
Also some change in serialization - same as in other places by now, do use existing values as defaults values when they are not found instead of resetting them to 0.

e5c8a75d40 Document deviant ITexture::lock behaviour for EDT_SOFTWARE drivers
Software driver sometimes works with original image (in 2D) and sometimes with POT version of the image (in 3D).
That is probably useful so it can draw the UI in best quality while having relative fast 3D.
The problem is that lock() only returns one data - so it decided to return the original data and then in unlock it updates the other data. But lock() data usually depends on getSize() so using EDT_SOFTWARE like other drivers causes crashes.
Not sure what the best solution here would be (maybe more flags or more lock functions?), so I just document the deviating behaviour and leave it as is.

7fd0f2b1fb COBJMeshFileLoader: Avoid memory leak when handling files with invalid vertex indices
Thanks @sfan5 for report and patch
Was part of the Minetest commit 80e1609 patch which was applied earlier
(couldn't apply this with the rest as the rest could be fixed in Irrlicht 1.8, while this one is about new Irrlicht 1.9 code)

cd70803500 Add warning about rotateXZBy using right handed rotation
Rest of Irrlicht is using left-handed rotatations.
But 2d vector rotations all uses ccw which is kinda the same direction as this one if you consider those as rotations around Y, so I guess that was maybe the reason back then.
