Revert of Skia roll 6b0d6b4:b2f7fce

Revert of Skia roll 6b0d6b4:b2f7fce (patchset #1 of https://codereview.chromium.org/516563003/)

Reason for revert:
It broke some antialiasing tests on Win7, see:
http://build.chromium.org/p/chromium.webkit/builders/WebKit%20Win7
http://build.chromium.org/p/chromium.webkit/builders/WebKit%20Win7/builds/19724/steps/webkit_tests/logs/stdio

The output has some odd comma added after each character. It doesn't seem to be a rebase problem.
