Detailed Description

Base interface for all DrawRangeElements* sub classes.

Implements the index-type-independent interface of the class. That is you can cast to DrawRangeElementsBase* and access its members without needing to know whether the actual class is a vl::DrawRangeElementsUInt, vl::DrawRangeElementsUShort or vl::DrawRangeElementsUByte.
