This file contains API changes between consecutive versions. You can get the
relevant information about all changes to the public Irrlicht API needed for
upgrading your code (esp. custom scene nodes and GUI elements) to a new Irrlicht
version. Since all changes are incremental you should skip forward to the
version you use right now and check each note until you reach the desired
version.
Please note that the changes described here do not contain functional changes,
but only syntactical ones. Also, new methods are not documented here and
have to be looked up in the API documentation instead.

Basically, all changes have to be reflected in user code where used. Removed
and renamed methods are obviously not existant anymore. A hint is usually given
for such changes on how to remedy the situation.
Changed signatures of methods might go unnoticed. That need not be a bad thing,
e.g. for changes from s32 to u32 the parameters are usually automatically
converted by the compiler. However, one should be careful when writing custom
scene nodes or GUI elements. It might happen that the methods are not properly
chosen as candidates for virtual overloading. So always check that methods in
the user code have the proper signatures just as the interface versions. The
change hint will help to identify necessary changes.

Changes for Version 1.4
-----------------------
This release had many changes in API method signatures. Many methods have been
made const, also several parameter types were changed. The two most noticeable
changes (which almost every user of the Irrlicht API will come across) are the
renaming of IUnknown to IReferenceCounted and const-ref change of the SEvent
structure of the OnEvent method. Another important change: DirectX8 support is
now by default disabled, enable the define in IrrCompileConfig.h to restore the
old behavior.

Changes for Version 1.4.1
-------------------------
Since this version is a backward compatible bugfix release, the API changes are only a few. None of them should result
in uncompilable code. Newly found warnings might point out wrongly used variables, additional casts or type changes in the
app should easily fix that. The only change which might go unnoticed by the compiler, but affect the application is the
changed initialization in SColorf. This was done to synchronize with other constructors from SColorf and SColor, though,
so the expectations are now much better met.
Also, OSX users have to adjust the defines in IrrCompileConfig, as we now also have OSX defines in Irrlicht style. It's now
even possible to build with X11 support under OSX without changes in the device code.

SColor.h
Changed signature (SColorf is now default initialized to alpha=1.0f)
	SColorf(f32 r=0.f, f32 g=0.f, f32 b=0.f, f32 a=1.f) : r(r), g(g), b(b), a(a) {}

IrrCompileConfig.h
Split the OSX define into platform and device (from old MACOSX define)
	_IRR_OSX_PLATFORM_ for Apple systems running OSX
	_IRR_USE_OSX_DEVICE_ for Cocoa native windowing on OSX

ISceneManager.h
Added new overload for getMesh with IReadFile instead of filename.
	virtual IAnimatedMesh* getMesh(io::IReadFile* file) = 0;

irrMath.h
Renamed method setbit
	REALINLINE void setbit_cond ( u32 &state, s32 condition, u32 mask )

ISceneNode.h
Changed signature (because the debug data enum values can be OR'ed to enable multiple debug data types)
	virtual void setDebugDataVisible(s32 state)
	s32 isDebugDataVisible() const
	s32 DebugDataVisible;

matrix4.h
Changed signature (Added return values to some methods)
	inline CMatrix4<T>& setbyproduct(const CMatrix4<T>& other_a,const CMatrix4<T>& other_b );
	CMatrix4<T>& setbyproduct_nocheck(const CMatrix4<T>& other_a,const CMatrix4<T>& other_b );

	CMatrix4<T>& setScale( const vector3d<T>& scale );
	CMatrix4<T>& buildProjectionMatrixPerspectiveFovRH(f32 fieldOfViewRadians, f32 aspectRatio, f32 zNear, f32 zFar);
	CMatrix4<T>& buildProjectionMatrixPerspectiveFovLH(f32 fieldOfViewRadians, f32 aspectRatio, f32 zNear, f32 zFar);

	CMatrix4<T>& buildProjectionMatrixPerspectiveLH(f32 widthOfViewVolume, f32 heightOfViewVolume, f32 zNear, f32 zFar);
	CMatrix4<T>& buildProjectionMatrixOrthoLH(f32 widthOfViewVolume, f32 heightOfViewVolume, f32 zNear, f32 zFar);
	CMatrix4<T>& buildProjectionMatrixOrthoRH(f32 widthOfViewVolume, f32 heightOfViewVolume, f32 zNear, f32 zFar);
	CMatrix4<T>& buildCameraLookAtMatrixLH(...)
	CMatrix4<T>& buildCameraLookAtMatrixRH(...)
	CMatrix4<T>& buildShadowMatrix(const core::vector3df& light, core::plane3df plane, f32 point=1.0f);
	CMatrix4<T>& buildNDCToDCMatrix( const core::rect<s32>& area, f32 zScale);
	CMatrix4<T>& setTextureScale( f32 sx, f32 sy );
	CMatrix4<T>& setTextureRotationCenter( f32 radAngle );
	CMatrix4<T>& setTextureScaleCenter( f32 sx, f32 sy );
	CMatrix4<T>& setTextureTranslate( f32 x, f32 y );
	CMatrix4<T>& setM(const T* data);
Added overload (for one scale value for all axes)
	CMatrix4<T>& setScale( const T scale ) { return setScale(core::vector3d<T>(scale,scale,scale)); }

S3DVertex.h
Added operator
	bool operator<(const S3DVertex& other) const
	bool operator<(const S3DVertex2TCoords& other) const
	bool operator<(const S3DVertexTangents& other) const

irrString.h
Changed signature (int->u32, negative length didn't make sense)
	bool equalsn(const string<T>& other, u32 n) const
	bool equalsn(const T* const str, u32 n) const
New overload/missing method (completing the findLast... and find...Char methods)
	s32 findLastChar(const T* const c, u32 count) const
Changed signature (Added return value)
	string<T>& trim()

Changes for Version 1.4.2
-------------------------
This is once more a bugfix release of the 1.4 branch, and hence pretty API-consistent and backward compatible. The major reason to publish this release is the OpenGL bug, which made several OpenGL 2.x drivers run in SW emulation.
However, we also introduced some driver consistency fixes, which might affect your application's behavior. So read through the next points thoroughly.

SceneParameters.h (and general video driver behavior)
The way Irrlicht handles zbuffer writing with transparent materials has changed. This was an issue ever since, because the default behavior in Irrlicht is to disable writing to the z-buffer for all really transparent, i.e. blending materials. This avoids problems with intersecting faces, but can also break renderings. And this is now consistent for both OpenGL and Direct3D.
If transparent materials should use the SMaterial flag for ZWriteEnable just as other material types use the newly introduced attribute scene::ALLOW_ZWRITE_ON_TRANSPARENT like this:
SceneManager->getParameters()->setAttribute(scene::ALLOW_ZWRITE_ON_TRANSPARENT, true);
All transparent materials will henceforth work as specified by the material flag, until the scenemanager attribute is set to false.

SMaterialLayer.h
The texture matrix now uses irrAllocator for memory handling. This shouldn't be noticeable from the user application (besides fixed heap corruptions on Windows machines), but is still mentioned for completeness.

ISceneNode.h
Documentation error. The docs said that children of a scene node are not visible if the node itself is set to visible. This is of course wrong, children inherit non-visibility of the parent and are hence invisible if the parent is. If the parent is visible, the visibility flag of the child determines its status.

SColor.h
Removed methods (use the unsigned versions and cast in your app if necessary)
	inline s32 getRedSigned(u16 color)
	inline s32 getGreenSigned(u16 color)
	inline s32 getBlueSigned(u16 color)

IParticleSystemSceneNode.h
Changed default values (the old direction default was no real direction)
 	virtual IParticleAnimatedMeshSceneNodeEmitter* createAnimatedMeshSceneNodeEmitter(...)
	virtual IParticleCylinderEmitter* createCylinderEmitter(...)
 	virtual IParticleMeshEmitter* createMeshEmitter(...)

IBoneSceneNode.h
Changed signature (Made const)
	virtual E_BONE_SKINNING_SPACE getSkinningSpace() const=0;

IrrlichtDevice.h
Changed signature (Return value bool instead of void). Returns whether the event has been handled somewhere.
	virtual bool postEventFromUser(const SEvent& event) = 0;

Changes for Version 1.5
-----------------------
Another major release, so expect API breaks at several places. The changes
herein are described as a difference to Irrlicht 1.4.2.

The most noticeable changes are the speed factor of the FPS camera (now units/ms
instead of units/s, so divide the parameter by 1000.f) and the new interfaces
of the camera nodes, based on scene node animators. Custom camera nodes should
be adpated to this new scheme, although they might still work. Also, particle
sizes are now set and handled by the emitters, which requires a change of the
particle system constructor call or adaption of the setParticleSize method to
work on the emitters. A deprecation method is issued if the old scheme is used.
Light setting has also changed, the SLight struct is used in even less
situations than before, instead use methods in ILightSceneNode.

Other changes did change major parts of the underlying structures, but might go
unnoticed on the user level. This includes 32bit indices and Vertex Buffer
Objects. However, VBOs require the user to call setDirty on Meshes or
MeshBuffers after changes to the vertex or index data. The all need only to be
done once before the next render call, but again after subsequent changes later
on.


All Mesh types and MeshBuffers:
New methods for VBO support. Once VBOs are enabled for a meshbuffer, changes
will only be effective after a call to setDirty(). VBOs are enabled by default
for some scene nodes.
	virtual void setDirty(E_BUFFER_TYPE buffer=EBT_VERTEX_AND_INDEX);

All MeshBuffers:
Due to the 32bit support, it might happen that indices are stored as 32bit integers. The actual index type can be queried from a mesh buffer.
	virtual video::E_INDEX_TYPE getIndexType() const

IrrCompileConfig.h
Some new defines for configuring Irrlicht
_IRR_USE_WINDOWS_CE_DEVICE_ for Windows CE API based device
_IRR_COMPILE_WITH_JOYSTICK_EVENTS_ to enable joystick support (enabled by default)
_IRR_COMPILE_WITH_LWO_LOADER_ to enable the LWO mesh loader (enabled by default)
_IRR_COMPILE_WITH_OBJ_WRITER_ to enable the OBJ mesh writer (enabled by default)
_IRR_COMPILE_WITH_WAL_LOADER_ to enable the WAL image loader (enabled by default)
_IRR_USE_NVIDIA_PERFHUD_ for support of the PerfHUD tool (disabled by default)

SceneParameters.h
New parameter scene::OBJ_LOADER_IGNORE_GROUPS, which allows to ignore the group structure of obj files. It's disabled by default, meaning obj groups will be represented by separate meshbuffers.

SColor.h
Renamed method names of the SColorHSL class
	void fromRGB(const SColor &color);
	void toRGB(SColor &color) const;

ITexture.h
Added new parameter
	virtual void* lock(bool readOnly = false) = 0;

IMeshManipulator.h
Renamed methods (the old ones still exist, but are deprecated). The new methods also work on meshbuffers, not just meshes.
(renamed from scaleMesh)
	virtual void scale(IMesh* mesh, const core::vector3df& factor) const = 0;
(renamed from transformMesh)
	virtual void transform(IMesh* mesh, const core::matrix4& m) const = 0;

	virtual IMesh* createMeshWithTangents(IMesh* mesh, bool recalculateNormals=false, bool smooth=false, bool angleWeighted=false) const = 0;

IBillboardTextSceneNode.h
New interface replacing the multiple inheritance from bliiboard and text scene node previously used by the billboard text scene node.

IParticleSystemSceneNode.h
All emitters have minStartSize and maxStartSize parameters now, since partice size is handled by the emitters now.
Default value added
	virtual void setParticlesAreGlobal(bool global=true) = 0;

fast_atof.h
Signature change (return value changed from u32)
inline s32 strtol10(const char* in, const char** out=0)

Changes for Version 1.5.1
-------------------------
This release is a pure bugfixes release, with almost no visible API changes. All changes should be backward compatible (as it's just a minor release), but you have to recompile the app due to changes in the virtual method tables.

dimension2d.h
Fixed a bug in the operator+=, added operator-= and changed comparison to equal() method.
	dimension2d<T>& operator-=(const dimension2d<T>& other)

IrrCompileConfig.h
Added defines to check for the Irrlicht version in the code.
	IRRLICHT_VERSION_MAJOR
	IRRLICHT_VERSION_MINOR
	IRRLICHT_VERSION_REVISION
	IRRLICHT_VERSION_SVN // only defined if you're using a version from SVN, i.e. not officially released one

IrrlichtDevice.h
Added static method isDriverSupported which checks the driver support of the library
	static bool isDriverSupported(video::E_DRIVER_TYPE driver)

irrMath.h
Added iszero specialization for f64

	IrrXMLReaderUTF16* createIrrXMLReaderUTF16(IFileReadCallBack* callback, bool deleteCallback = false);
	IrrXMLReaderUTF32* createIrrXMLReaderUTF32(IFileReadCallBack* callback, bool deleteCallback = false);

Changes for Version 1.6.0
-------------------------
This releases has many changes in method signatures. The most obvious ones are signedness changes from s32 to u32. Since many templates won't accept both types, you need to change the ypes manually in your code. The other major change is from many different types of strings to the new class io::path. These changes should be transparent to the app, unless you need proper overrides in derived classes.
Finally, some deprecated methods have been removed, and some were simply renamed. Just check the API if some methods is not found anymore.

Changes for Version 1.6.1
-------------------------
This is again just a bugfix release. However, some minor API changes have happened. The most important one is the removal of lins anti-aliasing from SMaterial's default values. Please add that line smoothing flag to the materials you want to be smoothed. But note that this may lead to drastically reduced performance, if no multi-sampling is active.

IrrCompileConfig.h
Removed auto recognition of Solaris OS, please define the setting on your own if you need it
	_IRR_SOLARIS_PLATFORM_

IGUITreeView.h
removed methods (use automatically generated versions)
	IGUITreeViewNode() {}
	virtual ~IGUITreeViewNode() {}
	virtual ~IGUITreeView() {}

IFileSystem.h
new method
	virtual IFileList* createEmptyFileList(const io::path& path, bool ignoreCase, bool ignorePaths) =0;

SMaterial.h
Removed default value (EAAM_LINE_SMOOTH from AntiAliasing)
	ZBuffer(ECFN_LESSEQUAL), AntiAliasing(EAAM_SIMPLE), ColorMask(ECP_ALL),

IGUISkin.h
new enum value
	EGST_COUNT
