Theoretical question about programmable user shaders

[Nash]

I know it's still way too early to discuss this, but as per the posts on ZDoom about the possibility of fully programmable user shaders, I have a question:

Were this to become a reality... would it have the effect where pausing the game (either via Pause or opening the main menu) would not stop any of the animation or movement that's going on in the shaded textures? For example, currently in GZDoom, warping textures are not affected by pausing. I'm guessing it has to do with how the timer for the animated textures and the game timer has to be decoupled (a problem seen in ZDoom too) but IMO it would look more polished if that wasn't the cause (to be honest I feel that it should be "corrected" for ZDoom too, it just looks really awkward from an end-user POV that animated textures continue to animate while the game is paused).

The existing custom shaders (see [wiki]GLDEFS[/wiki]) are affected, yes.
