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.

Those are the common formats, but rest of image loaders should also call this some day.

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?

Based somewhat on a patch in Minetest from sfan5 594de99153
There might be more problems which may be the reason they checked for other values in Minetest, but don't have more info for now and so far this works.

Only needs one addItem function when using default parameters for icon.
Add default parameters for setIcon, insertIcon so they can be used easier with pure text.

Before the value was checked, but not put into the return variables.
Header update to show that information in kb not bytes (on all systems, was just documented wrong)
Some cleanup of code.

a) SpriteBank. error check on non existing textureNumber. Seen in broken Fonts. unified getFrameNr
b) CBillboardTextSceneNode. use getOriginalSize

- allow ICameraSceneNode to accept any values and correct in buildCameraLookAtMatrixLH with normalize_camera_direction.
if disabled defaults to the current v1.9 normalize
b) add initial Rotation to MayaCamera Constructor default 0,0
c) switchToMayaCamera in Examples. Clones FPSCamera default disabled

Note I also modified the bounds checks for CMemoryReadFile once more to unify it with how Minetest fixed it.
Due to some strange coincidence I had run into that bug yesterday for CMemoryReadFile and fixed it without realizing a fix was also part of a bunch of patches I had gotten 3 days earlier in the forum:

Loading whole file now in memory (unless it's already a memory file).
And avoiding lots of memory allocations otherwise by buffering token string in class object.
Was a bit unusable before for large files (several minute loading times now down to a second)-

Still can't read it though - reader needs SSkinMeshBuffer which only supports 16 bit so far
(changes in loader are just spelling fixes in comments)

Thanks @Foaly for the patch (https://irrlicht.sourceforge.io/forum/viewtopic.php?f=9&t=51441)
Applied with some minor changes.
Also mesh-type in that loader now set to EAMT_STATIC (was EAMT_OBJ before, probably some copy-pasting going on).

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)
git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6340 dfc29bdd-3216-0410-991c-e03cc46cb475
Also added a bit documentation about what it's purpose seems to be (hope I got it right...).

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).
git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6335 dfc29bdd-3216-0410-991c-e03cc46cb475
- 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.

Allows to find out which class a meshbuffer has.
I used the same kind of style as ISceneNode::getType. So using four CC codes and virtual functions (instead of type variable).

Avoid creating dummy arrays when we work with non array images.
Just a minor speed improvement.

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.
Example 22.MaterialViewer using new cube type. Also a few more beauty fixes there.

Other functions like getMaterialRendererName got switched to u32 in the past. I can see no reason why this one was left out, so changing it to be same as the rest.
git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6300 dfc29bdd-3216-0410-991c-e03cc46cb475
So uv-coordinates can now be modified directly (previously only possible via texture matrix).

Due an off-by-one error it went wrong where there a special character replacement for the second-last character going on.
So something like "<X" became "<" instead of "<X".
git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6295 dfc29bdd-3216-0410-991c-e03cc46cb475
Just safer. Could probably do in a lot more places... another time.

Also avoid potential heap overwrites in there.
Sadly I have no examples for OCT files and it doesn't seem like a very common format as I couldn't even find any examples online.
So just assuming my changes work.

Tiny speed hit, but old solution caused warnings.
And it was not very safe by assuming all non _WIN32 platforms would use 32 bit sizes for wchar_t.

I don't know enough about DeleD from Delgine to fix this.
But keeping the functions defined out as long as they don't get in the way.
Also I'm a bit suspicious about the license... for use in Irrlicht core only under zlib license?
That's not really zlib license then :-(
