Failing org.eclipse.ui.tests.forms.util.FormFontsTest because of Font

[HeikoKlare]

Some tests of org.eclipse.ui.tests.forms.util.FormFontsTest are failing because of Font initialization.
See eclipse-platform/eclipse.platform.ui#2960

Probably a regresseoin from eclipse-platform/eclipse.platform.swt#2087

Directly created in "ready" state, as it's an obvious regression from our changes to the Font class and tests allow to reproduce them.
