Based on patch by Robert Mader. - Rename IsMainWindowTransparent() to IsToplevelWindowTransparent() to reflect it's about toplevel windows only. - Split needsAlphaVisual to popupNeedsAlphaVisual for popup windows and toplevelNeedsAlphaVisual for toplevel ones. Each use a different kind of configuration when shape masks are used. - Implement nsWindow::ConfigureX11GLVisual() to configure visual for accelerated backend. - Remove mIsAccelerated attribute and use a local variable.
