Catch a few cases where an invalid text node index is passed into
the shape subsetter.

Not on any Unix, at least. I have no idea how deep entrenched is this

(GNOME/KDE3 seem to handle it fine), but at least in the UI show just
"All files" instead of "All files (*.*)").

Thanks to Roman Eisele for mentioning.

This reverts commit 9d88c67c.

- use the same fade in/out values that we use for headers/footers
- clicking on the line opens the menu too
- clicking outside the menu hides the button
- leaving the line or the button hides the button immediately

Add a try-catch, so in case setting crop data fails, the size data will
be still set.

This basically reverts e8f980d1 and
b0e993d4, while keeping callcatcher
happy.

This reverts commit cf33de27.

This breaks make bug 20033 detection on Linux. If this can not be reliably
detected on OSX, just disable parallelism for GNU make 3.81 on OSX in general,
but leave the detection intact for Linux.
