RecordFrameMetrics gets called on a variety of layers. Previously it would incorrectly set mZoom for a number of these layers. For scrollable container layers inside the main document, it would set the mResolution from the presShell's resolution, thus compounding the painted resolution. Furthermore, for iframes inside the document, it would assign mZoom the value from TabChild's mLastMetrics, which is only meant to apply to the top-level document. Prior to multi-apzc work these values were never used so it didn't matter but now they are so they should be assigned correctly.
