Update to address some of the comments and fix a couple bugs.

Linux and Mac Builds

Added builds for both, but I can't currently test them. Please leave a comment if you have any issues with them.

Render Distance

This seems to be a common complaint, so I added an option to increase the "render" distance. Note that this will also increase the distance between layers in the resulting autostereogram. I haven't found a way around this trade-off yet, which is why I didn't have a higher render distance in the first build -- v1 had a max distance of 10. The default is now 15, and the max is 20. Any more and the layers become a worse problem than the inability to see distant enemies. 

Filtering

For those who want a less blurry image, I added an option for point filtering. I personally think this is too jarring, and doesn't have any effect on the stereogram, but it can't hurt to have the option. :)

Greyscale

Added an option to make the pixels greyscale. They have a uniform spread in darkness, so it's more consistent than random color mode. Might help if you're colorblind or just don't like the random colors.

Bugs

-Fixed weapon shader, should appear as close as possible instead of fuzzy
