In the Mac window we have an element with -moz-appearance: -moz-window-titlebar underneath the tab bar. The tab bar has -moz-appearance: -moz-mac-vibrancy-dark and blocks out the "titlebar" completely.

With WebRender we don't do any client-side occlusion culling, so we create unnecessary images for covered nsDisplayThemedBackground items. This creates some overhead which we'd like to avoid.

The reason that -moz-appearance: -moz-window-titlebar is set on something invisible is to make double-clicking in the right areas of the window minimize or zoom the window. That's because there's special handling for this -moz-appearance value in nsChildView.mm.

I'm going to create new -moz-appearance values called -moz-mac-vibrant-titlebar-dark and -moz-mac-vibrant-titlebar-light which can be set on the tab bar while also achieving the correct double click behavior.

Oh no :(

I forgot to regenerate the devtools property database...

This backout is probably also going to trip up the servo sync bot.

Yeah... It would've been nice to not back it out directly, but asking on IRC.

Too late now I guess, oh well :(
