Description

As discussed with Hans Muller,

DataGroup element recycling strategy needs to be enhanced so that it supports jumps in displayed Indexes.

Example : At the moment, The following scenario will end with the DataGroup recycling nothing :

updateDisplayList pass 1 : Element 0 and 9 are shown.

updateDisplayList pass 2 : Element 3 is shown.

Expected :

After updateDisplayList pass 2, the indexes 1, 2, 4, 5, 6, 7, 8, 9 should be marked as free for reuse
