tuxtxt: better usage of screen space for PIP mode

Browse Source 
for the PIP mode (text with toptext list on the right and
small livetv picture at bottom right) the screen space was
wasted by keeping the overall aspect ratio (text + toplist
+ PIP) 4:3. Change this to keep the text AR to 4:3, shifting
it to the left and adding the toplist and PIP on the right
to completely fill the 16:9 screen.
