+ * https://stackoverflow.com/questions/10868958/what-does-sampler2d-store
+ * The sampler2D is bound to a texture unit. The glUniform call binds it to texture
+ * unit zero. The glActiveTexture call is only needed if you are going to use multiple
+ * texture units (because GL_TEXTURE0 is the default anyway).
