xorgproto is a single package containing:

    x11-proto/bigreqsproto

    x11-proto/xineramaproto
    x11-proto/xproto

Also included are proto headers for which we do not currently have a
package:

    applewmproto (unpackaged)
    panoramixproto (unpackaged)
    pmproto (unpackaged)
    windowswmproto (unpackaged)

Behind a "legacy" flag (which we choose not to implement) there are
headers for dead things:

    evieproto                (legacy, unpackaged)
    x11-proto/fontcacheproto (legacy)
    lg3dproto                (legacy, unpackaged)
    x11-proto/printproto     (legacy)
    x11-proto/xf86rushproto  (legacy)
