<https://webkit.org/b/119836> [GTK] ChromeClient::paint is susceptible to system time changes
Reviewed by Martin Robinson.
Instead of using WTF::currentTime() as the value of the last display occurrence,
WTF::monotonicallyIncreasingTime() should be used. The latter is not affected by
the changes is the system's time, which can cause a halt in the display updating.
