When capturing only one display, it is unnecessary to use
DoDuplicateAll, which allocates bitmap image memory for a rectangle
encompassing all screens and captures all displays. In this case, I
switch to DoDuplicateOne.
I have added an int parameter to GetNumFrameCaptured and
EnsureFrameCaptured to distinguish which display's skip behavior is
currently being executed.
After the modification, when capturing a single monitor in a
multi-monitor environment, only the bitmap image memory of the size of
the captured monitor will be allocated, rather than for all monitors.
