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

# Bigmem testing houserules:
#
# - Try not to allocate too many large objects. It's okay to rely on
# refcounting semantics, but don't forget that 's = create_largestring()'
# doesn't release the old 's' (if it exists) until well after its new
# value has been created. Use 'del s' before the create_largestring call.
#
# - Do *not* compare large objects using assertEquals or similar. It's a
# lengty operation and the errormessage will be utterly useless due to
# its size. To make sure whether a result has the right contents, better
# to use the strip or count methods, or compare meaningful slices.
#
# - Don't forget to test for large indices, offsets and results and such,
# in addition to large sizes.
#
# - When repeating an object (say, a substring, or a small list) to create
# a large object, make the subobject of a length that is not a power of
# 2. That way, int-wrapping problems are more easily detected.
#
# - While the bigmemtest decorator speaks of 'minsize', all tests will
# actually be called with a much smaller number too, in the normal
# test run (5Kb currently.) This is so the tests themselves get frequent
# testing. Consequently, always make all large allocations based on the
# passed-in 'size', and don't rely on the size being very large. Also,
# memuse-per-size should remain sane (less than a few thousand); if your
# test uses more, adjust 'size' upward, instead.
