Subject: Eliminate pinned Mesh data on managed heap by using IntPtrs to memory
 allocated on the unmanaged heap. This prevents fragmentation of the managed
 heap and the resulting stress on GC. A region with ~150,000 prims using ODE
 and Meshmerizer saw memory remain flat around 1.2GB as opposed to 1.5GB and
 continually growing due to pinned memory. This patch complements the unique
 mesh dictionary patch applied to Meshmerizer but is independent. The net
 effect is a 60-75% reduction in memory for our largest regions.
