           Summary: PNG alpha channel is ignored
           Product: digikam
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED

When showing thumbnails of PNG with alpha channel to mask areas of picture,
digikam ignore it.

Reproducible: Always

Steps to Reproduce:
1.Create a PNG with alpha channel and save with it
2.Show that PNG thumbnail on digikam


Actual Results:  
Whole PNG picture is showed.

Expected Results:  
Do not show alpha areas from image on thumbnails, like Gwenview does.

User can't distinguish between PNG images with and w/o alpha channel, so he
need to preview it.
