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.

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.

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).

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.

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)

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.

Previously we handled all sizes as unsigned, but Windows BMP files can have negative height to signal top-down images.
No clue about left-right (would be trivial to swap as well, but found no info so far if that would be correct)

Thanks @sfan5 for report and patch

Image size calculation could overflow s32 in one place (but not others where it was done correct), which first lead to wrong amount of memory getting allocated for image data and later crash in the CColorConverter.

Was creating 16-bit images for those before.
Could also support 24-bit images, but either we need another convert function or another palette for that (the 16 and 32 bit both work with 32 bit palettes, the 24 bit conversion function only with 24 bit palettes)
git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6533 dfc29bdd-3216-0410-991c-e03cc46cb475
TGA's can claim to use less palette colors than they later do.
We only support 8-bit palettes, so to make this safer lets just always allocate at least 256 bytes.

Removing includes which were not needed by headers
Note that if you include those headers directly (instead of including irrlicht.h) you may have to add some new includes now.
Thought I generally tried to avoid removing headers where it leads to too much changes in user-code
Reason was mainly that IntelliSense in VisualStudio 17.7 added a new feature which shows those unused headers :)
Has to be used a bit careful as it doesn't know about defines and other platforms
And I only did clean up public headers so far (will probably do some more later or another time)

Note: Due to OSX always failing merge OSX it's rather applying a second patch

Wasn't ever used by anything and not that well defined anyway.
So they all just passed it on to the drivers. And then sometimes the driver version was called and sometimes the IMaterialRendererServices version. So now everything just calls the driver - all places which need it have access to the driver anyway. Also made the driver version non-virtual for now. If someone actually really needs this for some reason I can add it back as virtual function directly in IVideoDriver. But I doubt it - the interface was hardly accessible until recently and originally only meant for internal stuff.
GLES version still to do, but checked them earlier and they also just do nothing with it.

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.

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.
git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6469 dfc29bdd-3216-0410-991c-e03cc46cb475
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.
