VIGS: Replace glRasterPos with glWindowPos

We should always use glWindowPos instead of glRasterPos, because
values passed to glWindowPos are neither transformed by the current
modelview and projection matrices, nor by the viewport-to-window transform. This
yields more accurate results, unlike glRasterPos, which may have
rounding errors and as a result raster position may become invalid and
entire drawing operation will have no effect
