Fast way to render lots of spheres

	Setup:
	1. Index buffer containing N quads (each 2 triangles), where N is the max amount of spheres. Repeating pattern of {0,1,2,1,3,2} + K*4.
	2. No vertex buffer.

	Render N*2 triangles, where N is the number of spheres you have.

	Vertex shader:
	1. Sphere index = N/4 (N = SV_VertexId)
	2. Quad coord: Q = float2(N%2, (N%4)/2) * 2.0 - 1.0
	3. Transform sphere center -> pos
