Fixed potential access violation in QPixmap::copy() for <32 bit pixmaps.
QImage is supposed to maintain the invariant that each scan-line begins
on a 4-byte boundary, so we need to verify that this is the case before
using the optimized path of short-cutting QImage::copy() by referencing
the source image's bits directly.
