Determines if value1 and value2 can be non-trivially unioned.
Any two values can be trivially unioned by adding both of them
to a GstValueList. However, certain types have the possibility
to be unioned in a simpler way. For example, an integer range
and an integer can be unioned if the integer is a subset of the
integer range. If there is the possibility that two values can
be unioned, this function returns true.
Parameters
value1: any
a value to union
value2: any
another value to union
Returns boolean
true if there is a function allowing the two values to be unioned.
