Thanks for your explanation; this all makes sense now. DisableDevice was
changed to free the sprite back on 2012-06-06 in commit
df1704365e700d3cf1d36a241bdfc479159a8df7

Looks like we've been leaking the cursor stuff for a while now. And, it
looks like the FreeSprite call is entirely unnecessary in CloseDevice as
DisableDevice is always called first from RemoveDevice.
