By forcing offscreen rendering, I believe I meant hacking Wine so that it
always uses redirected/offscreen GL rendering even it it thinks it shouldn't
need to. This is automatically done by Wine when drawing to a child windows,
there's no way for an app to "force" it (short of creating a child window).
IIRC, what needs to happen is Wine needs to use offscreen GL rendering when a
window has WS_CLIPCHILDREN, but apps tend to set that flag even if they don't
use child windows (needlessly causing redirected GL rendering). That's what I
remember anyway, but I could be wrong.
