/**
* Sets the given mouse cursor. The mouse cursor will be in effect whenever
* the mouse is over the given instance until it is set again by another
* call. Note that you can hide the mouse cursor by setting it to the
* <code>PP_MOUSECURSOR_TYPE_NONE</code> type.
*
* This function allows setting both system defined mouse cursors and
* custom cursors. To set a system-defined cursor, pass the type you want
* and set the custom image to 0 and the hot spot to NULL. To set a custom
* cursor, set the type to <code>PP_MOUSECURSOR_TYPE_CUSTOM</code> and
* specify your image and hot spot.
*
* @param[in] instance A <code>PP_Instance</code> identifying the instance
* that the mouse cursor will affect.
*
* @param[in] type A <code>PP_MouseCursor_Type</code> identifying the type of
* mouse cursor to show.
*
* @param[in] image A <code>PPB_ImageData</code> resource identifying the
* custom image to set when the type is
* <code>PP_MOUSECURSOR_TYPE_CUSTOM</code>. The image must be less than 32
* pixels in each direction and must be of the system's native image format.
* When you are specifying a predefined cursor, this parameter must be 0.
*
* @param[in] hot_spot When setting a custom cursor, this identifies the
* pixel position within the given image of the "hot spot" of the cursor.
* When specifying a stock cursor, this parameter is ignored.
*
* @return PP_TRUE on success, or PP_FALSE if the instance or cursor type
* is invalid, or if the image is too large.
