A class that enables initialization and termination of the TVG engines.

Initializes TVG engines.
TVG requires the running-engine environment. TVG runs its own task-scheduler for parallelizing rendering tasks efficiently. You can indicate the number of threads, the count of which is designated threads. In the initialization step, TVG will generate/spawn the threads as set by threads count.
| [in] | engine | The engine types to initialize. This is relative to the Canvas types, in which it will be used. For multiple backends bitwise operation is allowed. |
| [in] | threads | The number of additional threads. Zero indicates only the main thread is to be used. |
| Result::Success | When succeed. |
| Result::FailedAllocation | An internal error possibly with memory allocation. |
| Result::InvalidArguments | If unknown engine type chosen. |
| Result::NonSupport | In case the engine type is not supported on the system. |
| Result::Unknown | Others. |

Terminates TVG engines.
| [in] | engine | The engine types to terminate. This is relative to the Canvas types, in which it will be used. For multiple backends bitwise operation is allowed |
| Result::Success | When succeed. |
| Result::InsufficientCondition | In case there is nothing to be terminated. |
| Result::InvalidArguments | If unknown engine type chosen. |
| Result::NonSupport | In case the engine type is not supported on the system. |
| Result::Unknown | Others. |
