Крайне сомнительно.
Хотя я не до конца знаю, как программно реализована функция мультитач.
Может она спасет.

Icons in Win32

What's in There?

The Win32 API provides a function for determining the characteristics of an icon, given its HICON handle. This function is GetIconInfo. GetIconInfo fills out an ICONINFO structure with the information pertaining to the HICON. The ICONINFO structure contains the following information:

typedef struct _ICONINFO { // ii

BOOL fIcon; // TRUE for icon, FALSE for cursor
DWORD xHotspot; // the x hotspot coordinate for cursor
DWORD yHotspot; // the y hotspot coordinate for cursor
HBITMAP hbmMask; // handle to monochrome AND mask bitmap
HBITMAP hbmColor; // handle to device dependent XOR mask bitmap
} ICONINFO;

Given this information, an application can calculate the information needed to write the icon to a file. The AND mask and XOR mask DIB bits can be obtained with calls to GetDIBits on the two bitmaps in this structure.
