https://bugs.webkit.org/show_bug.cgi?id=96064

Reviewed by Simon Fraser.

Partial load test for a PNG image with no alpha: receive a partial number of image
bytes and stall forever. The partial image should be decoded and drawn and the green
<img> background should be visible.

* fast/images/resources/lenna.png: Added: this PNG image has no alpha.
* http/tests/images/png-partial-load-no-alpha-expected.png: Added.
* http/tests/images/png-partial-load-no-alpha-expected.txt: Added.
* http/tests/images/png-partial-load-no-alpha.html: Added.
* platform/chromium/http/tests/images/png-partial-load-no-alpha-expected.png: Added.
* platform/mac/TestExpectations: Add an IMAGE failure for the mac port.
