* Update MonoGame references to 3.8.2.1105
* Vector2.Rotate is not built into MonoGame
* Update to net8
* Update version number
* Update changelog
* Deprecate Vector2.Rotate for MonoGame only
* Deprecate it but don't error it so API doesn't break for others.
* Moved `TextureRegion2D` and `NinePatchRegion2D` into Graphics namespace
These are used for more than just texture atlas related things and are primarly for working with `Texture2D` instances and creating sub textures from them. Moving them to Graphics namespace where `Texture2D` lives in MonoGame
* Dropped the `2D` suffix from `TextureRegion2D` and `NinePatchRegion2D`
* Moved `RectanglExtensions` to project root
This moves the extensions for `Rectangle` to the same relative namespace location as `Rectangle` is in MonoGame.
* Renamed to `Rectangle.Extensions.cs`
* Separate `Rectangle` from `RectangleF` extensions
* Added `GetRelativeRectangle` method
* Updated documentation
* Added `GetRelativeRectangle` method
* Updated documentation
* Top-level namespace
* Remove whitespace
* Move properties up
* Top-level namespace
* Don't recreate structs for `Bounds` and Size`
By having the property return a new struct, this allocates on the stack during situations like a loop during draw.
* Size should be `Size` not `SizeF` value
Textures deal in pixels (ints not floats)
* Removed setter for `Texture` property
Texture should not be set after region is created
* Added UV properties
* Refactor constructors
* Added documentation
* Added license header
* Make it an actual extension method
* Added `GetSubRegion` extension methods for `TextureRegion`
* Update documentation about ObjectDisposedException
* Move const values to top
* Resolve errors from`TextureRegion` refactor
* Update unit tests for TextureRegion refactor
* Started NinePatch rework
* Refactored NinePatch
* Update for texture region constructor change
* Remove ninepatch from atlas
* Moved `TextureAtlasExtensions` into `SpriteBatch.Extensions`
These are extension methods for the sprite batch
* Updated to use new `DrawTextureRegion` method after rename
* Renamed to NinePatchJsonConverter
* Removed `GetRegion<T>`
TextureAtlas no longer contains nine patch regions, so this method isn't needed
* Update after `NinePatchRegion2DJsonConverter` name change
* Resolve errors from NinePatch refactor
* TextureAtlas rework
* Renamed `TextureRegion` to `Texture2DRegion`
* Moved ContentReaders to new Content\ContentReaders directory
* Moved TextureAtlasJsonConvert to Serialization directory
* Adjusted name from `Texture*` to `Texture2D*`
* Update runtimereader and runtimettype strings
* Update file header
* Created initial project to move BitmapFont too
* XMl, Text, and Binar reading now supported for BMFont
* Refactor BittmapFont
* Update content pipeline from BitmapFont refactor
* Update changelog
