Detailed Description

Renders a series of framebuffers onto screen. This is a relatively simple way of allowing organization of multiple framebuffers. But layer management is a bit scuffed and could be made more intuitive. How, that's a different question.
How to use:

ShaderProgram_t shader; // Initialized somewhere above
// Init layer renderer
LayerRenderer layers;
// Add a new layer, and you can note down the index number
// The layers will be rendered in order of what you define it, so to reorganize layers
// you can just reorder the order they are initialized.
int first = layers.AddLayer<FramebufferRenderer>(shader, window);
int second = layers.AddLayer<FramebufferRenderer>(shader, window);
 
// Initialize the frame by doing this:
// .. Inside render loop
NewFrame(window); // Will clear all framebuffers
BeginDraw(first);
// .. some drawing
EndDraw(first);
BeginDraw(second);
// .. More drawing
EndDraw(second);
 
// Now this will be drawn at the end
DrawAllLayers();
