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
# f.close() is not thread-safe: calling it at the same time as another
# operation (or another close) on the same file, but done from another
# thread, causes crashes. The issue is more complicated than it seems,
# witness the discussions in:
#
# http://bugs.python.org/issue595601
# http://bugs.python.org/issue815646
