Carl Simonson cd7ad3e15e Catch and throw PNG exceptions - fixes
The png library uses setjmp/longjmp to throw exceptions when reading. If this
is not set up, the png library calls abort(). This change handles the errors
and throws a C++ exception instead.

This issue was found by testing images from pngsuite at
http://www.schaik.com/pngsuite/. These images are included and a unit test was
added to test both images that should be successful and images that should
throw an exception.

like viewers, converters and editors. All (as far as that is possible)
formats supported by the PNG standard are represented.
The suite consists of the following files:
- PngSuite.README - this file
- PngSuite.LICENSE - the PngSuite is freeware
- PngSuite.png - image with PngSuite logo
- PngSuite.tgz - archive of all PNG testfiles
- PngSuite.zip - same in .zip format for PCs
