Functions

	Name	Description
void	AddTexture2D ( UTexture2D* NewTexture, const FIncomingTextureArrayDataEntr... )	Adds a texture to the texture array.
void	BeginPreventReallocation()	Prevents reallocation from removals of the texture array until EndPreventReallocation is called.
void	EndPreventReallocation()	Restores the ability to reallocate the texture array.
uint32	GetNumSlices()	Returns the number of slices(textures) in this array.
int32	GetNumValidTextures()
int32	GetTextureIndex ( const UTexture2D* Texture )	Returns the index of a given texture in the texture array.
void	RemoveTexture2D ( const UTexture2D* NewTexture )	Removes a texture from the texture array, and potentially removes the CachedData entry if the last ref was removed.
void	UpdateResource()	Initializes the texture array resource if needed, and re-initializes if the texture array has been made dirty since the last init.
void	UpdateTexture2D ( UTexture2D* NewTexture, const FIncomingTextureArrayDataEntr... )	Updates a CachedData entry (if one exists for this texture), with a new texture.

		Name	Description
	uint32	GetSizeX()	Returns the width of the texture in pixels.
	uint32	GetSizeY()	Returns the height of the texture in pixels.

Overridden from FRenderResource

		Name	Description
	void	InitRHI()	Called when the resource is initialized. This is only called by the rendering thread.
