TKGetAnimateMessageInfo
4/8/2010
This function retrieves the movement information for any animate messages sent by Windows Auto Gesture. This feature enable the content in a window to scroll automatically in response to flick and pan gestures.
To automatically handle gesture scrolling, WS_VSCROLL or WS_HSCROLL (or both) styles must be included in the target window with scroll ranges that are set correctly.
After an application calls TKSetWindowAutoGesture and specifies the WAGIF_OWNERANIMATE flag, messages are sent to the window procedure when the content is animated. The application should call this function for each animation message to retrieve the correct values for that message.
