MSDN says that the cursor image set with SetCursorProperties can be shown as a 
user cursor if it has a size of 32x32 pixels. Otherwise the cursor is 
emulated like we do it at already in swapchain.c, 

So if the cursor image is 32x32 pixels, upload it to a gdi cursor, and do not 
upload it to a gl texture(doine in SetCusorProperties with the preload call), 
and do not draw it in present. Activate the user cursor in ShowCursor.

If the cursor is not 32x32 pixels then disable the gdi cursor, and draw the 
cursor as it is done now(upload to a gl texture, call Blt in present.

I don't know how to set a gdi cursor, but you can find the image in the d3d 
surface at surface->resource.allocatedMemory. Be aware that allocatedMemory 
may be NULL if the image is just stored in a gl texture, so the cleaner way 
is to call IWineD3DSurface::LockRect to retrieve the image.
