[trunk] Invisible text not drawn at all

Setup: trunk SVN rev. 4623; Qt lib 4.7.3; Ubuntu 11.04

Steps:

1) Open or create any score
2) Make sure "Display | Show Invisible" is checked
3) Set any text (title, staff text, tempo text, ...) as invisible

Expected result: the text is drawn with the 'invisible gray'.
Result: the text is not drawn at all.

Hint: in function ScoreView::paint() (file scoreviewcpp), when elements to be drawn are collected (line 1633), invisible text elements are not even included in the ell element list by function Page::items(const QPointF& p).
