786736 - Initialize nsSVGOuterSVGFrame::mFullZoom to the actual value in its ctor

Status: RESOLVED FIXED

(Core :: SVG, defect)

Description

[Jonathan Watt [:jwatt]]

I noticed while debugging a different bug that in nsSVGOuterSVGFrame::Reflow we end up passing FULL_ZOOM_CHANGED to NotifyViewportOrTransformChanged on first reflow because the initial value of mFullZoom doesn't match PresContext()->GetFullZoom(). That results in us wastefully calling NotifySVGChanged() and recursing over the frame tree.
