wip distortion update
Finishing adjusting rift distortion to use HMDinfo and calculated values in place of fixed values.
Scale factor enabled, correct scaling to fit horizontal.
Last commit did the opposite of what it said. This one actually does turn the correct scaling factor back on. It also fies the projection shift (multiplication was in the wrong order causing a translate then projection rather than translation of projection.)
Re-enabled fixed function transform adjustments. Changed to use standard ViewAdjustment rather than separate calculations. Updated aaaaaaaa profile.
