2017-04-10Guard against negative shift in nVal calculationDan Sinclair
It's possible for the nVal to become negative as it is shifted. This Cl changes nVal to be a checked_numeric and bails out if the shift is invalid.

2017-04-10Use checked_numeric to guard shiftDan Sinclair
It's possible for the RANGELEN[NTEMP] value to be larger then 32. This will make the shift invalid if the 1 is an int. This CL changes to 1L and uses the CheckedNumeric to validate that the result is inside the needed range for an int.

2017-04-10Guard against negative shift in jbig2 huffman initializationDan Sinclair
Depending on the code table, it's possible to have the largest PREFLEN value in the huffman table to be > 32. This will, potentially, cause the calcuation of ((FIRSTCODE[i - 1] + LENCOUNT[i - 1]) << 1 to overflow the int value and cause a negative shift. This Cl checks the shift value and failes the initialization if we would shift a negative value.

- All callers of CFX_DIBitmap methods use nullptr as the ICC Transform. - The CFX_ScanlineCompositor is always initialized with a null ICC transform.
