[0.8.8] major graphics problems on OSX 10.7.5, low gfx fix

[sparr]

The demo works fine, as far as I can tell. I was able to navigate the menus and play the game with no problems.

I downloaded the latest alpha and now encounter the following graphics glitches:

The menu and options interfaces are missing background (the grey boxes that should be around/behind all the buttons and text). I can see the prompt for my login and password, and the button text for skipping or submitting, but I can't see the button outlines, or the text fields to type into. I can see the labels for all the options menu items, but I can't see the checkboxes. etc

The game graphics are completely corrupted. I can see text for objectives and prompts, and some outlines, but all of the tiles show mostly-monochrome garbage. I am attaching a screenshot of this.

I tried deleting my "~/Library/Application Support/factorio" folder, but this had no effect. I finally managed to guess the location of the options checkboxes, so I turned on Low Graphics mode and everything is working fine now.
