MeshCacheParams::MeshCacheParams

MeshCacheParams(PCDefaultsType = PC_Defaults);
MeshCacheParams(ConsoleDefaultsType);
MeshCacheParams(const MeshCacheParams& src);

Default MeshCacheParams constructor for PC/Consoles and the copy constructor. 

On PCs, more memory can be occupied and a large staging buffer is required for building batches since there is no read access to Vertex Buffers. 

On Consoles, due to tighter memory conditions, smaller memory blocks can be used by default along with a smaller limit. Staging buffer can be small since video memory is typically readable.
