Using NvgSharp in MonoGame or FNA

Adding Reference

There are two ways of referencing NvgSharp in the project:

1. Through nuget(works only for MonoGame and Stride):

   • https://www.nuget.org/packages/NvgSharp.MonoGame/

2. As source code(works for all supported engines):

   a. Clone this repo.

   b. Add src/XNA/NvgSharp.{Engine}.csproj to the solution.

   • If FNA is used, then FontStashSharp should be cloned too. The overall folder structure is expected to be following:

Stencil

NvgSharp requires Game to be created with stencil. That could be archived by setting PreferredDepthStencilFormat to DepthFormat.Depth24Stencil8 in the GraphicsDeviceManager creation.

I.e.

public Game1()
{
	_graphics = new GraphicsDeviceManager(this)
	{
		PreferredBackBufferWidth = 1000,
		PreferredBackBufferHeight = 600,
		PreferredDepthStencilFormat = DepthFormat.Depth24Stencil8
	};
}

## Context Creation
Add following field to the Game class:
```c#
	private NvgContext _context;

And following code to the LoadContent method:

	_context = new NvgContext(GraphicsDevice);

Drawing

Add following code to Draw method to render a red circle:

	_context.BeginFrame(_graphics.PreferredBackBufferWidth, _graphics.PreferredBackBufferHeight, 1.0f);

	_context.FillColor(Color.Red);
	_context.Circle(100, 100, 20);
	_context.Fill();

	_context.EndFrame();
