Description:
------------
If gdImageConvolution() is applied to an image with a transparent
background, there can be black pixel artifacts (at the upper edge
of opaque parts, and at the top left of the image), what appears
to be a bug.
Test script:
---------------
ext/gd/tests/bug47946.phpt
Expected result:
----------------
No black pixels
Actual result:
--------------
Black pixel artifacts
