[Bug 92309] Box drawn around cursor in multiple 3D games

Based on what you said, I would think that it should be possible to detect when an invalid pre-multiplied alpha bitmap is in use. Is that true in all circumstances or is there more nuance to that? If it is true, I would think it'd be worth correcting for this error on the library side, though the problem is actually in the games.

How would the xserver know what the game intends in the cursor image?
