Image-Square-0.01_4

Changes for version 0.01_4

Tests still fail on different builds of GD. Now using PNG as input image and native GD format for output.

The previous tests failed due to the GD->jpeg method not being consistent across Perl versions. Now we are using PNG images instead as these should be more consistent!
Added 'Error Handling' section to POD and reference to the GitHub repository.

Crop and resize an image to create a square image
