Do the actual drawing in the paint event

Historically, because of two-stage drawing, LyX has been painting on a
Pixmap, and this pixmap is copied to screen at paint event time.

Now that we have three-stage drawing, it is possible to delay the
painting to actual paint event and avoid the intermediate Pixmap.

Known bug: the cursor is never erased.
