Bug 227053 – [GLIB] REGRESSION(r277896): fast/canvas/canvas-imageSmoothingEnabled.html and fast/canvas/canvas-imageSmoothingQuality.html are failing

• Component: New Bugs
• Status: RESOLVED DUPLICATE

[Diego Pino]

r277896 change imageSmoothingQuality default value to 'Low' for all platforms, since that's how defined in the specification.

That change made 2 tests start failing:

  fast/canvas/canvas-imageSmoothingEnabled.html [ Failure ]
  fast/canvas/canvas-imageSmoothingQuality.html [ Failure ]

 Test that restoring actually changes smoothing and not just the attribute value. We are restoring to a point where imageSmoothingEnabled is set to false.
