📄 Description

Correctly sets the time input on the pixelShaderSettings struct, which was previously hard-coded to 0.0f.

PR Checklist

Detailed Description of the Pull Request / Additional comments

I added a private field to DxEngine to store the timestamp for when a custom shader is first loaded. The field is initialized in _SetupTerminalEffects(), and the calculated time value (seconds since the timestamp) passed to the actual shader is set in _ComputePixelShaderSettings().

There remains an issue with with jerky animation due to the renderer not repainting when the window contents are not updated (see discussion in the original issue). - Fixed in #9091

This is basically my first time writing C++; constructive review is enthusiastically welcomed 🙂

Validation Steps Performed

I manually tested using a variety of simple shaders that rely on time input for animation.
