Sampled Page Top Color: take additional snapshots further down the page to see if the sampled top color is more than just a tiny strip https://bugs.webkit.org/show_bug.cgi?id=225323
Reviewed by Beth Dakin.
Source/WebCore:
Add a `SampledPageTopColorMinHeight` setting that controls how far down the sampled page top
color needs to extend in order for us to not bail. If the value > 0, we take an additional
snapshot at (0, SampledPageTopColorMinHeight) and (width, SampledPageTopColorMinHeight),
comparing each to the snapshot directly above (e.g. (0, SampledPageTopColorMinHeight) is
compared to (0, 0)) using the `SampledPageTopColorMaxDifference`. Depending on the value, if
the color across the top of the page is only a small strip, these extra snapshot comparisons
will prevent a resulting color from being derived.
