Remove Crop Tool in Shopping Cart

Pretty sure I already know the answer to this, but I'll give it a go anyway as it's still bugging me.

I've been annoyed for a while about the inability to remove the cropping and rotate functions from the shopping cart, and an e-mail today from a confused buyer only further cemented my annoyance.

Does anyone know of any CSS hacks to hide the buttons & crop tool, maybe a color hack to make them invisible?

I set different price lists according to image aspect ratios, so have no need for a tool that lets potential customers play around with the framing.
