class FMutableTaskGraph

Mutable Tasks System.

Allows launching tasks in different threads:

Concurrency between tasks in the Mutable Thread is forbidden by chaining all tasks through their prerequisites.

LOW PRIORITY MUTABLE TASKS:

Only one Low Priority task can be launched at the same time. This is because once a Task Graph task is launched, it can not be canceled. To allow canceling them, the system holds them until it can ensure that its execution will be imminent (no other tasks running).
A Low Priority task will not be launched if one of the follow conditions is true (in order):

There is a task Low Priority task running.

Flag bLaunchMutableTaskLowPriority is false.

There is a Normal Priority task running (unless time limit).
