Functions

	Name	Description
void	CloneViaCopyImage ( TOpenGLTexture* Src, uint32 InNumMips, int32 SrcOffset, int32 DstOffset )	Clone texture from a source using CopyImageSubData
void	CloneViaPBO ( TOpenGLTexture* Src, uint32 InNumMips, int32 SrcOffset, int32 DstOffset )	Clone texture from a source going via PBOs
bool	GetAllocatedStorageForMip ( uint32 MipIndex, uint32 FaceIndex )	Accessors to mark whether or not we have allocated storage for each mip/face.
uint32	GetLockSize ( uint32 MipIndex, uint32 ArrayIndex, EResourceLockMode LockMode, uint32& DestStride )	Returns the size of the memory block that is returned from Lock, threadsafe
void *	GetNativeResource()	FRHITexture override.
void *	GetTextureBaseRHI()
bool	IsCubemap()
bool	IsDynamic()	Accessors.
bool	IsStaging()
void *	Lock ( uint32 MipIndex, uint32 ArrayIndex, EResourceLockMode LockMode, uint32& DestStride )	Locks one of the texture's mip-maps.
void	Resolve ( uint32 MipIndex, uint32 ArrayIndex )	Resolved the specified face for a read Lock, for non-renderable, CPU readable surfaces this eliminates the readback inside Lock itself.
void	SetAllocatedStorage ( bool bInAllocatedStorage )	Set allocated storage state for all mip/faces.
void	SetAllocatedStorageForMip ( uint32 MipIndex, uint32 FaceIndex )
void	Unlock ( uint32 MipIndex, uint32 ArrayIndex )	Unlocks a previously locked mip-map.
