Subject: [PATCH] Fix unsigned/signed mismatch warning in KTX file reading

On MSCV x86 (32bit) the comparison of qsizetype with
std::numeric_limits<quint32>::max() leads to a warning.
This patch adds a static cast to avoid the warning.

This is an ammendment to 28ecb523ce8490bff38b251b3df703c72e057519
