Optimize Texture Binding and Shader Specialization Checks (#3399)

Browse source 
* 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.
