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

from Tkinter import *

# This example program creates a scroling canvas, and demonstrates
# how to tie scrollbars and canvses together. The mechanism
# is analogus for listboxes and other widgets with
# "xscroll" and "yscroll" configuration options.
