// There was a bug in BitVector.sizeInBytes() that caused it to return a
// smaller-by-one value (ex. 1465 instead of 1466) if the number of bits
// in the vector is not 8-bit aligned. In QRCodeEncoder::InitQRCode(),
// BitVector::sizeInBytes() is used for finding the smallest QR Code
// version that can fit the given data. Hence there were corner cases
// where we chose a wrong QR Code version that cannot fit the given
// data. Note that the issue did not occur with MODE_8BIT_BYTE, as the
// bits in the bit vector are always 8-bit aligned.
//
// Before the bug was fixed, the following test didn't pass, because:
//
// - MODE_NUMERIC is chosen as all bytes in the data are '0'
// - The 3518-byte numeric data needs 1466 bytes
// - 3518 / 3 * 10 + 7 = 11727 bits = 1465.875 bytes
// - 3 numeric bytes are encoded in 10 bits, hence the first
// 3516 bytes are encoded in 3516 / 3 * 10 = 11720 bits.
// - 2 numeric bytes can be encoded in 7 bits, hence the last
// 2 bytes are encoded in 7 bits.
// - The version 27 QR Code with the EC level L has 1468 bytes for data.
// - 1828 - 360 = 1468
// - In InitQRCode(), 3 bytes are reserved for a header. Hence 1465 bytes
// (1468 -3) are left for data.
// - Because of the bug in BitVector::sizeInBytes(), InitQRCode() determines
// the given data can fit in 1465 bytes, despite it needs 1466 bytes.
// - Hence QRCodeEncoder.encode() failed and returned false.
// - To be precise, it needs 11727 + 4 (getMode info) + 14 (length info) =
// 11745 bits = 1468.125 bytes are needed (i.e. cannot fit in 1468
// bytes).
