>+        Move OpenGL display mask to screen data struct.

>+        Currently, the OpenGL display mask is a global in the WebContent process. This is not correct in all cases, since
>+        it is possible to have two Web views in the same WebContent process, displayed on different displays. This can be
>+        resolved by moving the OpenGL display mask to a new ScreenData struct, containing information specific to each
>+        display. The display ID of the host window is used to find the OpenGL display mask when needed. This patch makes
>+        the host window available when creating an IOSurface, in order to find the right OpenGL display mask. If no host
>+        window is available, the OpenGL display mask of the main display is used.
>+
>+        No new tests, since testing this requires two Web views in the same WebContent process, displayed on
>+        two different monitors.

>+        Currently, the OpenGL display mask is a global in the WebContent process. This is not correct in all cases, since
>+        it is possible to have two Web views in the same WebContent process, displayed on different displays. This can be
>+        resolved by moving the OpenGL display mask to a new ScreenData struct, containing information specific to each
>+        display. The display ID of the host window is used to find the OpenGL display mask when needed. This patch makes
>+        the host window available when creating an IOSurface, in order to find the right OpenGL display mask. If no host
>+        window is available, the OpenGL display mask of the main display is used.
