Message:
fix BadMatch error when embedding on some windows When embedded, st fails with BadMatch error if the embedder's window has non-default colormap/depth/visual. This commit fixes that by creating st's window inside root and then reparent it into embedder. The reference window for dc.gc is also changed to match root's visuals. A similar commit had been made for dmenu[1]. See this issue[2] on github for context.
