Public Member Functions
void	Reset ()
	Free the memory of the readback texture.

ezGALFenceHandle	ReadbackTexture (ezGALCommandEncoder &ref_encoder, ezGALTextureHandle hTexture)
	Starts a readback of a texture. A new readback texture will be created if the current one does not match the new texture.

ezReadbackTextureLock	LockTexture (const ezArrayPtr< const ezGALTextureSubresource > &subResources, ezDynamicArray< ezGALSystemMemoryDescription > &out_memory)
	Same as ezGALDevice::LockTexture, but checks that the fence has been reached. If not, returns an invalid lock object.
