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
differences.

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

Scale all images to the nearest rounded integer, and if there's still
any scaling factor left over, pass it on to the subsequent bilerp code.
Should avoid artifacts when tiling scaled images.

in the downsamplebitmap GM; I verified that this fixes the issue

992c7b03ef7914a18bfd78e965b0b4c99a5f5672 31-Jul-2014 Cary Clark <caryclark@google.com> Add standard fonts to all GMs.

Allow GM results to be compared across machines and platforms by
standardizing the fonts used by all tests.

This adds runtime flags to DM to use either the system font context (the
default), the fonts in the resources directory ( --resourceFonts ) or a set
of canonical paths generated from the fonts ( --portableFonts ).

This CL should leave the current DM results unchanged by default.

If the portable font data or resource font is missing when DM is run, it
falls back to using the system font context.

The create_test_font tool generates the paths and metrics read by DM
with the --portableFonts flag set, and generates the font substitution
tables read by DM with the --resourceFonts flag set.

If DM is run in SkDebug mode with the --reportUsedChars flag set, it
generates the corresponding data compiled into the create_test_font tool.

All GM tests set their typeface information by calling either

sk_tool_utils::set_portable_typeface or
sk_tool_utils::portable_typeface .

(The former takes the paint, the latter returns a SkTypeface.) These calls
can be removed in the future when the Font Manager can be superceded.

There was a clean up opportunity left over after
https://skia.googlesource.com/skia/+/bcbc1788b478b1e54079318ad073e8490aa66fae, that could make use of the default parameter of GetResourcePath() function to make some call sites cleaner.

We decided to make it in a separate CL to make reviewer's and author's life easier, so we could catch errors and/or mistakes easily.

- Rename TileGrid -> Quilt to avoid the name overload.
- Tag all failing GMs with kSkipTiled_Flag.

You may be wondering, do any GMs pass? Yes, some do! And that trends towards all of them as we increase --quiltTile.

Two GMs only fail in --quilt mode in 565. Otherwise all GMs which fail are skipped, and those which don't fail aren't. (The 8888 variants of those two GMs are skipped even though they pass.)

We've tested this CL plumbed into Chrome and done benchmarking with excellent results.

This CL can land independent of any Chrome changes; it's completely internal to skia.

1) always generate mipmaps if we detect that we are downsampling.
2) pre-scale the image if we detect that we are upsampling
(currently valid for scale+translate only)
3) A few miscellaneous bug fixes related to image scaling.

Still need SSE/Neon versions of these image scalers.
