fast/forms/text-control-intrinsic-widths.html fails on Mac if Word/Office fonts are installed

Several metrics will be off, including Arial.

The fix is to remove /Library/Fonts/Microsoft/

I think you have to restart the ATSServer to get any application to notice.  (I used sudo killall ATSServer)

Non-working patch

Attaching some hacking here, but this doesn't work. Apparently there is no way to disable fonts for just one process on Mac.

[Simon Fraser (smfr)]

Maybe the scripts should just tell users to disable the fonts themselves?

WebKit learns of available fonts only through NSFontManager and through AppKit’s and Core Text’s default fallback lists. I think that the latter would never include user-installed fonts, so for the purposes of this bug, I believe that DumpRenderTree can swizzle a handful of NSFontManager methods to filter out undesirable families and fonts.

[Alexey Proskuryakov]

This wasn't effective at fixing fast/forms/text-control-intrinsic-widths.html as of OS X Yosemite - fonts in /Library/Fonts/Microsoft took precedence over ones in /Library/Fonts.

Additionally, fallback did include /Library/Fonts/Microsoft fonts.

I re-fixed the first issue in bug 142720.
