Seungha Yang a516c79ac9 d3d11window: Prefer full color range for display target colorspace
We don't need to preserve input color range for transformed target
color space. Also some GPUs doesn't seem to be happy with 16-235
color range for RGB color space.
Also, since our default display target color space is
DXGI_COLOR_SPACE_RGB_FULL_G22_NONE_P709, choosing full color range
would make more sense.
