prompts appear whenever pictures are
shown. You can decide whether these
prompts shall be seen by default or not.

The GVPE always starts with decoding the
full picture and keeps in memory all available
information. Zooming in, zooming out and
panning through the picture are then just a
matter of displaying the available information.
The consequence of this method is that it takes a
bit longer to get the first view but that afterwards
all other manipulations are rendered much faster.
