When a Window is created for holding BViews attached to an offscreen bitmap,

always behave as if within a transaction. Otherwise all drawing calls to such
BViews wait for the server to finish the request. This change gives a tremendous
speed boost for these situations and is compatibly with BeOS, since there you
also had to call Sync() before drawing a bitmap that was painted with attached
views.
