Possible bug in StringBuffer::SetGrowSize

[8bit]

Just looking through the SDK I found this possible error.
I could be wrong but I believe there is a missing +1.

LibOVRKernel/Src/Kernel/OVR_String.cpp

void StringBuffer::SetGrowSize(size_t growSize) 
{ 
    if (growSize <= 16)
        GrowSize = 16;
    else
    {
        uint8_t bits = Alg::UpperBit(uint32_t(growSize-1));
		size_t size = (size_t)1 << bits;
        GrowSize = size == growSize ? growSize : size;
    }
}

Shouldn't this be

void StringBuffer::SetGrowSize(size_t growSize) 
{ 
    if (growSize <= 16)
        GrowSize = 16;
    else
    {
        uint8_t bits = Alg::UpperBit(uint32_t(growSize-1)) + 1;
		size_t size = (size_t)1 << bits;
        GrowSize = size == growSize ? growSize : size;
    }
}

Anyway, just putting this out there in case people are running into seg faults with strings.
