Accidentally commit "382c580 evas: add support for .9.png file to PNG loader."
adding the 9 patch feature with small code refactoring made use of setjmp
evas_image_load_file_data_png calls _evas_image_load_file_internal_head_png,
and _evas_image_load_file_internal_head_png calls setjmp and returns without
problem. And png_read_row calls longjmp. This causes jumping into a function
which was exited. Problematic png file will be attached.
Save calling environment i.e. call setjmp, after returning from
