Bug 1517976 - Test that resetting WindowUtils.isFirstPaint doesn't clobber APZ scroll position. r=botond We need to setup a case where the visual viewport is smaller than the layout viewport. Faking a pinch zoom through touch events is imprecise, whereas calling windowUtils.setResolutionAndScaleTo(value > 1) to simulate the equivalent effect of a pinch-zoom on the page led to the subsequent scroll attempt failing quite often even after calling waitForApzFlushedRepaints(). So instead, we set up a very wide layout viewport through the meta viewport tag, which on Desktop means additionally enabling the dom.meta-viewport.enabled pref.

#include "nsITaskbarPreview.idl"
interface nsITaskbarPreviewButton;

 * nsITaskbarWindowPreview
 * This interface represents the preview for a window in the taskbar. By
 * default, Windows implements much of the behavior for applications by
 * default. The primary purpose of this interface is to allow Gecko
 * applications to take control over parts of the preview. Some parts are not
 * controlled through this interface: the title and icon of the preview match
 * the title and icon of the window always.
 * By default, Windows takes care of drawing the thumbnail and preview for the
 * application however if enableCustomDrawing is set to true, then the
 * controller will start to receive requestPreview and requestThumbnail calls
 * as well as reads on the thumbnailAspectRatio, width and height properties.
 * By default, nsITaskbarWindowPreviews are visible. When made invisible, the
 * window disappears from the list of windows in the taskbar for the
 * application.
 * If the window has any visible nsITaskbarTabPreviews, then the
 * nsITaskbarWindowPreview for the corresponding window is automatically
 * hidden. This is not reflected in the visible property. Note that other parts
 * of the system (such as alt-tab) may still request thumbnails and/or previews
 * through the nsITaskbarWindowPreview's controller.
 * nsITaskbarWindowPreview will never invoke the controller's onClose or
 * onActivate methods since handling them may conflict with other internal
 * Gecko state and there is existing infrastructure in place to allow clients
 * to handle those events 
 * Window previews may have a toolbar with up to 7 buttons. See
 * nsITaskbarPreviewButton for more information about button properties.
