Bug Type:         Bug
Bug description:libpng warning from imagecreatefromstring

Description:
------------
imagecreatefromstring is writing a warning message to stderr that can
not be suppressed by '@' or captured by the error handler.  It should
emit a proper PHP warning instead.

I have the following version of libPNG:

php -i | grep -i libpng
libPNG Version => 1.6.19+apng

To run the test script, download the sample PNG image from here:
http://imgbox.com/BzOXLiOr

Note: libPNG 1.5.18 on PHP 5.6.17 for Windows does not have this
problem.

Test script:
---------------
php -r
'@var_dump(imagecreatefromstring(file_get_contents("1CCHOHSULGF78KW.png")));'



Expected result:
----------------
resource(6) of type (gd)

Actual result:
--------------
libpng warning: iCCP: known incorrect sRGB profile
resource(6) of type (gd)
