[PATCH 0/1] MR5568: windowscodecs: Avoid implicit cast changing value.

[Alistair Leslie-Hughes (＠alesliehughes)]

This appear to be introduced with commit 12f73ed9d851.

When This->stride is negative (bottom up image) it converts the multiplication to an UINT.
Thus causing the pointer to be incorrect when y > 0.
