====== CanvasState ======

[[/doc/sfml_rust/canvas/canvas_state/struct.CanvasState.html|Documentation]]

===== Details =====

	The gist of this class is basically draw everything 2D and have all the resources to do so. It holds binary buffer blobs for resources, it's own compiled shaders, render_pass, and all of the vertex buffers in order to draw those binary buffer blobs. 

	**window_size_dependent_setup** is currently hosted inside this class. If a second graphics class is added I will add some shared library for this to live.
	
	**render_pass **the render pass is created with our depth stencil/color data **D32Sfloat_S8Uint **attachment for the render output. This is highly shader dependent. Also depends on the DynamicState


===== Interface =====

	Generally there is a get for handle and pointer and a load (or create) for each of the stored items.
	
	The class then interacts with these stored items by taking and executing a list of operations to perform on them. 

	CanvasFrame
		Going to need some interface for getting vertices.
		Some interface for getting the texture or image
