/** @file

	This file configures Ogre's memory allocators. You can modify this
	file to alter the allocation routines used for Ogre's main objects.

	When customising memory allocation, all you need to do is provide one or
	more custom allocation policy classes. These classes need to implement:

	@code
	// Allocate bytes - file/line/func information should be optional, 
	// will be provided when available but not everywhere (e.g. release mode, STL allocations)
	static inline void* allocateBytes(size_t count, const char* file = 0, int line = 0, const char* func = 0);
	// Free bytes
	static inline void deallocateBytes(void* ptr);
	// Return the max number of bytes available to be allocated in a single allocation
	static inline size_t getMaxAllocationSize();
	@endcode

	Policies are then used as implementations for the wrapper classes and macros 
	which call them. AllocatedObject for example provides the hooks to override
	the new and delete operators for a class and redirect the functionality to the
	policy. STLAllocator is a class which is provided to STL containers in order
	to hook up allocation of the containers members to the allocation policy.
	@par
	In addition to linking allocations to policies, this class also defines
	a number of macros to allow debugging information to be passed along with
	allocations, such as the file and line number they originate from. It's
	important to realise that we do not redefine the 'new' and 'delete' symbols 
	with macros, because that's very difficult to consistently do when other
	libraries are also trying to do the same thing; instead we use dedicated
	'OGRE_' prefixed macros. See OGRE_NEW and related items.
	@par
	The base macros you can use are listed below, in order of preference and 
	with their conditions stated:
	<ul>
	<li>OGRE_NEW - use to allocate an object which have custom new/delete operators
		to handle custom allocations, usually this means it's derived from Ogre::AllocatedObject. 
		Free the memory using OGRE_DELETE. You can in fact use the regular new/delete
		for these classes but you won't get any line number debugging if you do.
		The memory category is automatically derived for these classes; for all other
		allocations you have to specify it.
	</li>
	<li>OGRE_NEW_T - use to allocate a single class / struct that does not have custom
		new/delete operators, either because it is non-virtual (Vector3, Quaternion),
		or because it is from an external library (e.g. STL). You must
		deallocate with OGRE_DELETE_T if you expect the destructor to be called. 
		You may free the memory using OGRE_FREE if you are absolutely sure there
		is no destructor to be called. 
		These macros ensure that constructors and destructors are called correctly 
		even though the memory originates externally (via placement new). Also note 
		that you have to specify the type and memory category so that the correct 
		allocator can be derived, when both allocating
		and freeing.
	</li>
	<li>OGRE_NEW_ARRAY_T - as OGRE_NEW_T except with an extra parameter to construct
		multiple instances in contiguous memory. Again constructors and destructors
		are called. Free with OGRE_DELETE_ARRAY_T.
	</li>
	<li>OGRE_ALLOC_T - use to allocate a set of primitive types conveniently with type safety. 
	This <i>can</i> also be used for classes and structs but it is <b>imperative</b> that
	you understand that neither the constructor nor the destructor will be called. 
	Sometimes you want this because it's more efficient just to grab/free a chunk of
	memory without having to iterate over each element constructing / destructing.
	Free the memory with OGRE_FREE. </li>
	<li>OGRE_MALLOC - the most raw form of allocation, just a set of bytes. 
		Use OGRE_FREE to release.</li>
	<li>_SIMD and _ALIGN variants - all of the above have variations which allow
		aligned memory allocations. The _SIMD versions align automatically to the
		SIMD requirements of your platform, the _ALIGN variants allow user-defined
		alignment to be specified. </li>
	</ul>
	Here are some examples:
	@code
	/// AllocatedObject subclass, with custom operator new / delete
	AllocatedClass* obj = OGRE_NEW AllocatedClass();
	OGRE_DELETE obj;
	AllocatedClass* array = OGRE_NEW AllocatedClass[10];
	OGRE_DELETE [] obj;
	/// Non-virtual or external class, constructors / destructors called
	ExternalClass* obj = OGRE_NEW_T(ExternalClass, MEMCATEGORY_GENERAL)(constructorArgs);
	OGRE_DELETE_T(obj, ExternalClass, MEMCATEGORY_GENERAL);
	ExternalClass* obj = OGRE_NEW_ARRAY_T(ExternalClass, 10, MEMCATEGORY_GENERAL);
	OGRE_DELETE_ARRAY_T(obj, NonVirtualClass, 10, MEMCATEGORY_GENERAL);
	/// Primitive types
	long* pLong = OGRE_ALLOC_T(long, 10, MEMCATEGORY_GENERAL);
	OGRE_FREE(pLong, MEMCATEGORY_GENERAL);
	/// Primitive type with constructor (you can mismatch OGRE_NEW_T and OGRE_FREE because no destructor)
	long* pLong = OGRE_NEW_T(long, MEMCATEGORY_GENERAL)(0);
	OGRE_FREE(pLong, MEMCATEGORY_GENERAL);
	/// Raw memory
	void* pVoid = OGRE_MALLOC(1024, MEMCATEGORY_GENERAL);
	OGRE_FREE(pVoid, MEMCATEGORY_GENERAL);
	@endcode
	OGRE_ALLOC_T is also the route to go for allocating real primitive types like 
	int & float. You free the memory using OGRE_FREE, and both variants have SIMD
	and custom alignment variants.
