Bug # 10324: dix: Allow arbitrary value ranges in GetPointerEvents

Browse source 
Don't use a possitive value as a marker for if a max-value
is defined on the valuators. Use the existence of a valid
value range instead. This will also make it possible to
define arbitrary start and end-values for min and max as
long as min < max.
