src_hstart.
src_vstart means the vertical intercepted starting place of the input signal source. It
cannot be larger than the input vertical resolution.
src_vsize means the vertical intercepted size of the input signal source.
Note： src_vsize plus the src_vstart cannot be larger than the input vertical resolution.
0 means the vertical size of using the original signal source and it is invalid to use
src_vstart.
x0 means the horizontal starting pixel point of the window
y0 means the vertical starting pixel point of the window
x1 means the horizontal ending pixel point of the window
y1 means the vertical ending pixel point of the window
For example：1,
The instruction means: open a window with the ID number 0 on the second group of split
joint screen, this window is shown on the second output screen of the split joint screen;
the window input signal source is 1, and the input signal will not be intercepted.
Return value：WIN_IDERR：Means the ID of the window already existed.
NET_OK: Means the instruction executes successfully.
2.
The instruction means: open a window with the ID number 1 on the first group of split
joint screen, this window is shown on the first output screen of the split joint screen; the
window input signal source is 2. Meanwhile, the area of upper left corner 512x512 of the
second signal source will be intercepted.
Return value：WIN_IDERR：Means the ID of the window already existed.
NET_OK: Means the instruction executes successfully.
Note：Please refer to instruction 15 for the location of the intercepted signal source and
the size of signal source.
