The high level API is:

• Event
• Sprite
• Texture
• Window

With those component you can create every graphic thing that you want.

The window need a name and sizes then they will work out of the box just draw on it. That's all.

event let you handle most of event, mouse or keyboard and you just have to link them with a match to handle it like in the example.

Texture can be linked for all drawable objects however you should use Rc on them for now.

you can create a sprite from a texture and then draw it on a window.
