GLbitfieldspecifying a bitwise combination of flags controlling the flushing behavior. May be
GLint64specifying a timeout (in nanoseconds) for which to wait for the sync object to become signaled. Must not be larger than

gl.ALREADY_SIGNALED: Indicates that the sync object was signaled when this method was called.
gl.TIMEOUT_EXPIRED: Indicates that the
timeouttime passed and that the sync object did not become signaled.
gl.CONDITION_SATISFIED: Indicates that the sync object was signaled before the
gl.WAIT_FAILED: Indicates that an error occurred during the execution.
