<h3>Log Message</h3>
<pre>Changing TiledBacking velocity should schedule a tile revalidation
https://bugs.webkit.org/show_bug.cgi?id=144123
Reviewed by Tim Horton.
Source/WebCore:
Changing the velocity parameters on the TileController affect the computed
coverage rect, so whenever we make a change to velocity data that could
affect the outcome (basically any non-zero old or new velocities),
schedule a layer flush.
* platform/graphics/TiledBacking.h:
(WebCore::VelocityData::velocityOrScaleIsChanging):
* platform/graphics/ca/TileController.cpp:
(WebCore::TileController::setVelocity):
Source/WebKit2:
Drive-by fix: use the FrameView& that we have already.
* WebProcess/WebPage/ios/WebPageIOS.mm:
(WebKit::WebPage::updateVisibleContentRects):</pre>
