Eskil Abrahamsen Blomfeldt a4e2f2e687 Fix possible crash in QImage::pixel() 
QImage::pixel() assumed that the color table was valid
for the values in the bitmap. This was always wrong
for indexed images with explicit no color table set and
was wrong for mono images that were constructed from
preexisting data.

For mono images, we default to a black/white color table,
like we do when constructing with uninitialized data.

For indexed image, we always default to no color table,
but instead of crashing in pixel(), we warn and return
an undefined value.

[ChangeLog][QtGui][Image] Fixed possible crash in QImage::pixel()
for mono or indexed images.
