Working HMD rotations but broken memory optimizations. Try and bring working HMD back to the main branch and leave the memory changes alone for the time being
Added pix profiling messages. Unsure if release is being called on render target
Fixed merge conflicts with master
Fixed crashing bug on d3d device resets. Culprit was a surface not being released from the screen rendertarget due to a pointer being overwritten at creation time, and the screen vertex buffer has been moved to managed DX memory since releasing it at reset time seemed to be releasing a DIFFERENT vbo (I don't even know where to begin with that)
Fixed crash on exit errors due trying to delete already deleted pointers
