Erm, it is a lucky bug. GQview fails to set the WM_CLASS for full screen. If I
rename the binary to helpme and run it the full screen WM_CLASS becomes "helpme,
Helpme", this will be fixed to become "fullscreen, GQview".

The dialogs now work above a full screen window because for 1.5.4 there was a
bug fix to 'Set dialogs as a transient of their originating window'.

All earlier versions of GQview did not tell the window manager the parent window
of the dialog, so had a problem of full screen hiding new dialogs. To 'fix' the
broken dialogs full screen had to be turned off whenever a dialog was displayed.

GQview 1.5.6 introduces a full screen option 'Stay above other windows' which
requests the window to be set above other windows :)  Unfortunately the option
is disabled when compiled with GTK+ 2.2.x as it uses a feature introduced in
GTK+ 2.4.

GQview 1.4.5 does not have the ability to configure the location of the full
screen window, therefor setting the FULLSCREEN window manager hint can be safely
used.

Perhaps "Active screen" would be better described as "Active screen: Full size".

The only time "Active screen" and "Screen :0.0, Full size" would differ is if
there is a second screen, for example the list would then also include "Screen
:0.1, Full size". But this is all theory as I have yet to even try a setup with
dual heads set to be :0.0 and :0.1.

IIRC, these are describing the effects of using the FULLSCREEN window manager
hint and how it effects the ability to place or size the window, and is why
GQview 1.5.4+ no longer uses the hint.
