Fixes to syborg-graphicswrapper.vcproj These changes allow syborg-graphicswrapper to link against the hostthreadadapter and khronosapiwrapper libraries built by the graphics.simulator component. The .vcproj file uses relative paths, which requires that the following three packages are laid out as follows: os/ graphics adapt/ graphics.simulator qemu

#include <w32std.h> 
#include "profiler.h"

#include <graphics/surfacemanager.h>
#include <graphics/surfaceupdateclient.h>
