Detailed Description

D3D11 doesn't support mapping the same buffer twice even if the regions don't overlap.

For performance we keep many buffers as one big buffer, but for compatibility reasons (with GL3/DX10 HW) we treat them as separate buffers.

This class takes care of mapping buffers once while allowing BufferInterface to map subregions of it as if they were separate buffers.
Remarks
This is a very thin/lightweight wrapper around D3D11's Map, thus: Caller is responsible for unmapping. Caller is responsible for proper synchronization. No check is performed to see if two map calls overlap.
