caryclark 65cdba6ba7 Revert of Revert of make gm background colors 565 compatible (patchset #1 id:1 of https://codereview.chromium.org/1184123002/)
Reason for revert:
underlying problem with portable refs deleted more than once fixed

Original issue's description:
> Revert of make gm background colors 565 compatible (patchset #2 id:20001 of https://codereview.chromium.org/1176243006/)

> Reason for revert:
> breaks many bots with refcnt error
>
> Original issue's description:
> > make gm background colors 565 compatible
> >
> > Change a batch of GM tests to convert their background color
> > so that it is representable in 8888 and 565.
> >
> > Enable portable text in those same tests to minimize platform

> >
> > In a couple of bitmap tests, use portable typefaces instead of
> > choosing 'Times' which may or may not be available on the platform.
