c5b349ddb0 Add IMeshBufffer::clone for buffer copies, use it in CMeshManipulator::createMeshCopy
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).

c58afe8038 IMeshLoader can now set hints to prefer 16/32 bit buffers. Obj loader can now load 32 bit buffers.
- 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.

64fc9113fc Split CNullDriver::checkImage into 2 functions to avoid some memory allocations in addTexture
Avoid creating dummy arrays when we work with non array images.
Just a minor speed improvement.

3dc5f8fd9f Replace more getSize() with getOriginalSize() calls in tests.
Textures involved had all power of two sizes anyway, so no real difference in this case, just a bit cleaner.

57f518737d vector3d scalar operator/ and operator/= no longer multiply by the inverse but use the expected division.
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.

b11c4c142c Remove several copy-constructors and assignment operators which did nothing special.
They all just implemented the same the default functions do.
This causes now warnings with newer gcc -Wdeprecated settings (otherwise they would have had to implement always both, but makes no sense as they did nothing special).

4a6d08d976 Clarify a bit in changes.txt the bug-case of rect::clipAgainst
(I was wondering why it worked for UI).
And run some tests (all seem fine... in 64bit, 32-bit has some older problem).

0368c5b09d IGUIEnvironment::drawAll has now a parameter to allow disabling the automatic resize to driver screensize.
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.

5d0b042a65 Use f64 version of reciprocal_squareroot in quaternion::normalize for more precision.
The f32 version jumped around more on gcc/linux (didn't do so with VisualStudio, mabye sqrt on VS already uses double internally).

0b71328102 Use BlendFactor only when MaterialType != EMT_ONETEXTURE_BLEND
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.

473ab1ea58 Unify checks if materials should use transparent render pass with new IVideoDriver::needsTransparentRenderPass function.
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?

2928a632a4 Material.ZWriteEnable is now of type E_ZWRITE instead of bool and ZWriteFineControl get removed (or merged into ZWriteEnable).
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).

c661373121 EMT_REFLECTION_2_LAYER and EMT_TRANSPARENT_REFLECTION_2_LAYER on OpenGL now same as D3D9 version.
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.
