Resolves#14966
When "Include mouse pointer" is checked in the Windows
version of the Create Screenshot plug-in, we used the
GetCursor () Win32 API to get the cursor icon. However,
this just returns a generic cursor rather than the current one
used.
This patch changes the code to use the hCursor property of
the CursorInfo struct that was already retrieved, which contains
the current cursor's icon instead of the generic one.
