	Record a command to copy the contents of one texture to another texture. The blit area is limited by the intersection of the texture coverage with respect the source region and destination origin. No work is encoded into the command buffer at this time.
bool	AddCopy (std::shared_ptr< Texture > source, std::shared_ptr< DeviceBuffer > destination, std::optional< IRect > source_region=std::nullopt, size_t destination_offset=0, std::string label="")
	Record a command to copy the contents of the buffer to the texture. No work is encoded into the command buffer at this time.
bool	AddCopy (BufferView source, std::shared_ptr< Texture > destination, IPoint destination_origin={}, std::string label="")
	Record a command to copy the contents of the buffer to the texture. No work is encoded into the command buffer at this time.
bool	GenerateMipmap (std::shared_ptr< Texture > texture, std::string label="")
	Record a command to generate all mip levels for a texture. No work is encoded into the command buffer at this time.
