Nak. The mask is expected by users, who *already* discard the mask when they know that the rendering will be identical without it. The existing renderproto was written to render a union of the glyph path, which accounts for overlapping glyphs quite succinctly. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
