This PR fixed several minor styling issues. These issues are mainly caused because I removed mat-typography class from the root because it has several margins not needed on KHI and we needed to override them everywhere.

  • simplified the revision color shader for highlighting effects not to become noise for users

Summary of Changes

Hello @kyasbal, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request overhauls the timeline visualization and overall application layout to resolve previous styling inconsistencies and improve the component's architecture. The changes aim to enhance the user experience through more robust resizing capabilities and refined visual elements, while also modernizing the underlying implementation for better performance and future development.

Highlights

  • Timeline Component Refactor: The core timeline component has undergone a significant refactor, transitioning from a custom WebGL rendering and resizing implementation to a new Angular signal-based architecture. This includes the introduction of TimelineFrameComponent and TimelineSmartComponent for improved structure and maintainability.
  • Layout and Resizing: The main application layout now utilizes the angular-split library for managing resizable panes, replacing a custom ResizingCalculator. This simplifies the resizing logic for side panes and the overall main view.
  • WebGL Shader Updates: The WebGL fragment shader for revision colors (revision-v2.color-fragment.glsl) has been updated to refine the rendering of icons, stripe patterns, and overall color blending for timeline items. Several older, custom WebGL shader files have been removed as part of the refactor.
  • Styling and UI Adjustments: Various minor styling issues have been addressed across the application, including adjustments to revision state colors, hover overlay appearance, font weights in timeline indices, and line heights in log views. The global mat-typography class has been removed from index.html.
  • New Scroll Calculators: Introduced HorizontalScrollCalculator and VerticalScrollCalculator classes to manage virtual scrolling, time-to-pixel conversions, and dynamic layout calculations for the timeline, enhancing performance and responsiveness.

Code Review

This pull request introduces a significant refactoring of the timeline component, moving from a custom WebGL-based rendering and resizing system to a new Angular signals-based component that leverages angular-split for layout management. This refactoring should improve maintainability and potentially the user experience. Additionally, several minor stylistic adjustments have been made to colors, transparencies, and font weights across various components. The removal of the mat-typography class from the root <body> is a deliberate step to gain more control over typography, as stated in the PR description.

* Add MSDF texture generation scripts (#445)

* Add MSDF texture generation scripts

To enable extensible and high quality font/icon rendering on WebGL2, this script precalculate MSDFs and bake it on textures.
These files are going to be used in the updated timeline v2 renderer.

* Removed font generation step from CI

The font atlas textures and its output JSON files are included in repository.
This design is because it won't be conflict a lot ,its easy to regenerate to merge. I'll integrate this step with CI later.
We don't need to run it on CI again.

* Applied fixes suggested by gemini

* Apply suggestions from code review
