/**
 * Sigma.js WebGL Renderer Node Program
 * =====================================
 *
 * Simple program rendering nodes as discs, shaped by triangles using the
 * `gl.TRIANGLES` display mode. So, to draw one node, it will need to store
 * three times the center of the node, with the color, the size and an angle
 * indicating which "corner" of the triangle to draw.
 * It does not extend AbstractNodeProgram, which works very differently, and
 * really targets the gl.POINTS drawing methods.
