12 * Per-screen information.
13 * Note that an EGL screen doesn't have a size.  A screen may be set to
14 * one of several display modes (width/height/scanrate).  The screen
15 * then displays a drawing surface.  The drawing surface must be at least
16 * as large as the display mode's resolution.  If it's larger, the
17 * OriginX and OriginY fields control what part of the surface is visible
18 * on the screen.
