Conditional Viewports
Any viewport can be displayed either permanently or conditionally. Defining a viewport
as %V(... will display it permanently.
%Vl('identifier',...) This tag preloads a viewport for later display. 'identifier'
is a single lowercase letter (a-z) and the '. . . ' parameters use the same logic as the
%V tag explained above.
%Vd('identifier') Display the 'identifier' viewport.
Viewports can share identifiers so that you can display multiple viewports with one
%Vd line.
%?C<%Vd(a)|%Vd(b)>
%Vl(a,10,10,50,50,-)
%Cl(0,0,50,50,c,c)
%Cd
%Vl(a,0,70,70,14,1)
%s%acThere you have it: Album art.
%Vl(b,20,14,50,14,1)
%t(1)%acWarning:;%t(.1)
%Vl(b,20,30,50,50,1)
%sNo album art found
%scheck your filenames.
