midispcur: Construct Picture objects lazily in case Render is disabled.
Reverts part of the effects of 518f3b189b6c8aa28b62837d14309fd06163ccbb,
"mi: don't thrash resources when displaying the software cursor across
screens". The per-screen cache is preserved, and the GCs are still
allocated eagerly, but now it doesn't construct pRootPicture until
somebody attempts to draw an ARGB cursor.
I noticed crashes in Xnest, which doesn't support the RENDER extension,
but I suspect other DDXes that support disabling that extension would
have had issues as well.
