Disable text component optimizations if shaders are used to modify text

[Aeltumn]

Currently using shaders to add text animations will break when using Noxesium with experimental UI optimizations because it is assumed text components do not change when rendered multiple times.

We should draw a component once every few seconds regardless and check if any pixels changed in which case we continue drawing that component actively (like with obfuscated text) until the pixels have been identical for some time. The setup of having BakedComponent objects control whether it needs re-drawing is the basis for this support.

Experimental UI optimizations have been reworked to support this.
