Subject: -fixed some strange display bugs depending of switch to qte 2.3.10

-inserted the missed (and asked for) feature setting a display brightness
 on the fly.
Known Bugs left: When starting with setting a document the image will not
displayed if too large. It is since switch to qte 2.3.10 eg. seems to be
a timing problem when loading cost too much time. I have no idea how to fix
it this moment.
