* Changes 1 * Changes 2 * Better ModifiedSequence handling This should handle PreciseEvents properly, and simplifies a few things. * Minor changes, remove debug log * Handle stage.Info being null Hopefully fixes Catherine crash * Fix shader specialization fast texture lookup * Fix some things. * Address Feedback Part 1 * Make method static.
