Minor - Adds dynamic screen depth and near controls - V14.4.0

Implements dynamic adjustment of screen depth and near clipping plane distances via the ImGui interface.

This allows users to modify the perspective projection in real-time, affecting the rendering of the scene.

The changes involve:
- Adding screen depth and near variables to the application class.
- Exposing these variables in the ImGui settings window.
- Adding functions to the application and d3d classes to update the projection matrix based on new screen depth and near values.
- Updates the sky sphere size to use world scale.
