Description

Determines the strategy how the index and vertex data of a mesh is handled (uploaded, downloaded, deletet, …). Different simple behaviors can be realized with this class directly, other strategies (e.g. with a more sophisticated memory management) can use this class as a base.

Note: All instances of this class should be created only once and re-used (they are probably never deleted)

Note: If a mesh does not have a data-strategy, the default strategy is used.

Note: If an implementation does make use of gl-calls, be carefull if the mesh is accesed from a non-gl-thread.
