[screenshot] Safari doesn't clip none

Description Alicia Boya García 2018-07-04 10:44:29 PDT 
The following test is failing on GTK since r233493-233495 (image only failure):

fast/text/multiple-text-shadow-overflow-layout-rect.html

The difference is very subtle (one line of pixels in a shadow)

My change seems the culprit. Sorry.

[screenshot] Safari doesn't clip

fast/text/multiple-text-shadow-overflow-layout-rect.html is a ref test.

-actual.png and -expect.png are clipped the upper part of the SVG font differently.

In the first place, this test case is a test to check the SVG font isn't clipped as the comment in the test case states.
I attached screenshot of Safari. It doesn't clip at all.
Comment 3 Fujii Hironori 2018-07-04 22:56:42 PDT 
Chrome deprecated SVG font support. Other browsers don't plan to support it.

It seems that WebKit doesn't claims to support SVG fonts.

Fixed and Unmarked in https://trac.webkit.org/changeset/233556/ .
But, the clipping issue still remains.
