Constructs a new cursor given a device, image and mask
data describing the desired cursor appearance, and the x
and y coordinates of the <em>hotspot</em> (that is, the point
within the area covered by the cursor which is considered
to be where the on-screen pointer is "pointing").
<p>
The mask data is allowed to be null, but in this case the source
must be an ImageData representing an icon that specifies both
color data and mask data.
<p>
You must dispose the cursor when it is no longer required.
</p>
@param device the device on which to allocate the cursor
@param source the color data for the cursor
@param mask the mask data for the cursor (or null)
@param hotspotX the x coordinate of the cursor's hotspot
@param hotspotY the y coordinate of the cursor's hotspot
@exception IllegalArgumentException <ul>
<li>ERROR_NULL_ARGUMENT - if device is null and there is no current device</li>
<li>ERROR_NULL_ARGUMENT - if the source is null</li>
<li>ERROR_NULL_ARGUMENT - if the mask is null and the source does not have a mask</li>
<li>ERROR_INVALID_ARGUMENT - if the source and the mask are not the same
size, or if the hotspot is outside the bounds of the image</li>
</ul>
@exception SWTError <ul>
<li>ERROR_NO_HANDLES - if a handle could not be obtained for cursor creation</li>
