Updated property access in `GLRenderer.cs` and `GLBindingStates.cs` to use consistent naming conventions. Enhanced `GLPrograms.cs` with null-conditional operators and pattern matching for safer property access and simplified type checks. Refactored parameter addition to `Hashtable` using collection initializer syntax for improved readability and maintainability.

- Refactored `Update` method in `GLGeometries.cs` to ensure geometry is of type `BufferGeometry` and handle `BufferAttribute` updates using a switch statement.
- Added dimension checks in `InitCamera` of `BuffergeometryExample.cs` and `InstancingDynamic.cs` to prevent invalid camera initialization.
- Implemented a safeguard in `LinesFatExample.cs` to avoid division by zero when calculating aspect ratio for `camera2`.

Implemented a null check for the variable `e` to ensure that the `currentExample` is only instantiated and loaded if `e` is not null. If `e` is null, a message "Invalid example info." is logged to the console to prevent null reference exceptions.

Updated multiple project files to target .NET 9.0 instead of .NET 8.0, including changes to the `TargetFramework` property in `FormsDemo`, `SilkDemo`, `SingleFormsDemo`, `SingleSceneSilkExample`, `THREE.OpenGL`, `THREE.Silk`, `THREE`, `THREESilkExample`, `WPFDemo`, and `WSLDemo`.

Retained and reformatted assembly metadata in `THREE.csproj`, while preserving the `AllowUnsafeBlocks` property. Some project and package references were modified or removed, indicating a cleanup of dependencies.

The `OutputType` for `FormsDemo` and `SingleFormsDemo` was changed to `WinExe`, and the `WPFDemo` project was updated to align with the new target framework.

These changes enhance compatibility with the latest .NET framework, potentially improving performance and modernizing development practices.

- Added `System.Net.Http`, `System.Text.RegularExpressions`, and `System.Text.Json` to multiple projects.
- Updated versions of `Pfim`, `SkiaSharp`, and `StbImageSharp` in `THREE.csproj`.
- Reformatted method signature for `ToSKBitMap` in `ImageExtension.cs` for consistency.

This reverts commit 8a2dc2c.

- Upgraded `ImGui.NET` to version `1.91.6.1` in multiple projects.
- Updated `Silk.NET` packages to version `2.22.0` in `THREE.Silk.csproj`.
- Changed `Pfim` version to `0.11.3` in `THREE.csproj`.
- Updated `StbImageSharp` to version `2.30.15` in `THREE.csproj`.
- Modified `ImGui.Selectable` method calls for better UI behavior.

The check for non-zero dimensions in the ClientRectangle
has been removed from the InitCamera method. This change
eliminates the `InvalidOperationException` that was thrown
when either width or height was zero, while keeping the
camera initialization logic intact.

- Removed and added mouse event handlers in Form1.Designer.cs for better event management.
- Introduced constants and a new LoadTexture method in DisplacementMapExample.cs to enhance readability and maintainability.
- Updated Init and Render methods in CinematicCameraExample.cs to improve scene setup and GUI control handling.
- Overall focus on improving code structure, readability, and user interaction capabilities.

- Deleted the `nuget.exe` binary file.
- Modified `ToSKBitMap` method signature and delegate in `ImageExtension.cs`.
- Removed commented-out methods in `ImageExtension.cs`.
- Updated `SkiaSharp` and `SkiaSharp.NativeAssets.Linux` versions in `THREE.csproj` and `WSLDemo.csproj`.
- Ensured consistent formatting for `glControl` in `Example.cs`.
- Simplified `InitCamera` method in `BuffergeometryExample.cs` to use `glControl.AspectRatio`.

This reverts commit 674aefc.

Removed dimension check for glControl and updated aspect
ratio calculation to use glControl.AspectRatio directly.

Refactor GLControl usage by replacing `OpenTK.WinForms.GLControl` with `OpenTK.GLControl.GLControl` for improved compatibility with .NET 6.0. Update OpenTK and related package versions to 4.9.3 and 4.0.2. Remove conditional compilation directives for a unified codebase. Adjust method calls to align with the updated OpenTK API. Remove `nuget.exe` to streamline package management with .NET CLI. These changes modernize the codebase and enhance OpenGL rendering capabilities.
