Also added a function that has extensive details about what the projection options mean, and set our near plane much closer (0.25 to 0.0625) and far plane much farther (100000.25 to 524288.0625). In the future we may completely remove the far plane (opting for an infinite one) and may possibly improve accuracy elsewhere using analysis of other floating point values.
