Skin variables for touchscreen targets (origional implementation by Jens Theeß)

Browse source 
%vs(name, [set|inc|dec], value [,max]) - name is the id, set sets the value, inc increments by value, dec decrements by value
%vg(name) - get the current value
%vl(name [,timeout]) - 'has it changed in [timeout]'?

values start at 1 and are all reset to 1 on skin load
