Remove SK_IGNORE_PROPER_FRACTIONAL_SCALING.

Remove SK_IGNORE_PROPER_FRACTIONAL_SCALING.

This causes Skia to use fractional bitmap scaling in Chromium, which is
necessary to avoid both record-time scaling and "seam" artifacts in bitmap
patterns.

Necessary suppressions in Blink layout tests are in this CL:

LGTM. You can also land expectations changes like this TBR, but regardless you
should watch the bots when it lands in case you missed any or the bot behavior
is not the same as the trybots.

Err, this is the Chromium-side config change. I need to land the Blink-side
TestExpectations change first.

TBRed the TestExpectations change as suggested. It will roll into Chromium
shortly.

LGTM, but should also wait for Mike to make sure there aren't any unexpected
side effects in Skia.

this flag existed only for chrome, so glad to have it removed.

humper, you should be able to remove the associated code from skia now.
