* page/EventHandler.cpp:
(WebCore::EventHandler::EventHandler):
(WebCore::EventHandler::clear): Clear long press state.
(WebCore::EventHandler::handleMousePressEvent): Start the long-press if the mouse press is a left
mouse press over a link.
(WebCore::EventHandler::eventMayStartDrag): We cannot start a drag if we've recognized a long press.
(WebCore::EventHandler::handleMouseReleaseEvent):
If we didn't recognize a long press, cancel the long press.
(WebCore::EventHandler::beginTrackingPotentialLongMousePress):
Begin the long mouse press by kicking off a timer. If the timer fires before the long press is
cancelled, the long press is recognized.
(WebCore::EventHandler::recognizeLongMousePress): Added. Trigger the long-press and disable other
actions like dragging.
(WebCore::EventHandler::cancelTrackingPotentialLongMousePress): Added. Cancel the long press by
clearing related state.
(WebCore::EventHandler::clearLongMousePressState): Added. Clear long press state.
(WebCore::EventHandler::handleLongMousePressMouseMovedEvent): Added. Cancel the long press if
the mouse moves outside a specified hysteresis interval.
(WebCore::EventHandler::handleMouseMoveEvent): Ask handleLongMousePressMouseMovedEvent whether to
return early and not update hovers, cursors, drags, etc.
(WebCore::EventHandler::dragHysteresisExceeded): Factor out the hysteresis bounds check into
mouseHysteresisExceeded().
(WebCore::EventHandler::handleDrag): Cancel long press upon starting drag.
(WebCore::EventHandler::mouseHysteresisExceeded): Added. General hysteresis function that takes an
arbitrary mouse movement threshold. Factored out from dragHysteresisExceeded.

Load the layout test result image diff HTML from a file, rather than having it inline in webkitpy

Reviewed by Dan Bates.

Tools:

Pull the HTML for the image diff file into a separate file, for easier hackability.

LayoutTests:

Add image-diff-template.html and expected result (crazy, but this is what we do
for results.html too).

Build fix for 32-bit.

* UIProcess/mac/ServicesController.mm:
(WebKit::ServicesController::ServicesController):
Don't dynamically refresh services in 32-bit apps. It's not possible
to write a 32-bit app with the Modern API, so this doesn't matter.

Unbreak webkitpy unit tests by checking for the existence of the image diff template
file before trying to open it (as the tests do for results.html).
