In the following files, replacing disp->mVisible with disp->IsVisible() is a BUG FIX: nsBlockFrame, nsBulletFrame, nsHRFrame, nsHTMLContainerFrame, nsImageFrame, nsTextFrame.
In all the other files, replacing disp->mVisible with disp->IsVisible() or disp->IsVisibleOrCollapsed() is merely a SYNTACTICAL CHANGE. The respective owners will later review the use of IsVisibleOrCollapsed() and in some cases replace it with IsVisible(). See bug 21701.
