-/* Integrator State
- *
- * This file defines the data structures that define the state of a path. Any state that is
- * preserved and passed between kernel executions is part of this.
- *
- * The size of this state must be kept as small as possible, to reduce cache misses and keep memory
- * usage under control on GPUs that may execute millions of kernels.
- *
- * Memory may be allocated and passed along in different ways depending on the device. There may
- * be a scalar layout, or AoS or SoA layout for batches. The state may be passed along as a pointer
- * to every kernel, or the pointer may exist at program scope or in constant memory. To abstract
- * these differences between devices and experiment with different layouts, macros are used.
- *
- * INTEGRATOR_STATE_ARGS: prepend to argument definitions for every function that accesses
- * path state.
- * INTEGRATOR_STATE_CONST_ARGS: same as INTEGRATOR_STATE_ARGS, when state is read-only
- * INTEGRATOR_STATE_PASS: use to pass along state to other functions access it.
- *
- * INTEGRATOR_STATE(x, y): read nested struct member x.y of IntegratorState
- * INTEGRATOR_STATE_WRITE(x, y): write to nested struct member x.y of IntegratorState
- *
- * INTEGRATOR_STATE_ARRAY(x, index, y): read x[index].y
- * INTEGRATOR_STATE_ARRAY_WRITE(x, index, y): write x[index].y
- *
- * INTEGRATOR_STATE_COPY(to_x, from_x): copy contents of one nested struct to another
- *
- * INTEGRATOR_STATE_IS_NULL: test if any integrator state is available, for shader evaluation
- * INTEGRATOR_STATE_PASS_NULL: use to pass empty state to other functions.
- *
- * NOTE: if we end up with a device that passes no arguments, the leading comma will be a problem.
- * Can solve it with more macros if we encounter it, but rather ugly so postpone for now.

+ * these differences between devices and experiment with different layouts, macros are used.
+ *
+ * Use IntegratorState to pass a reference to the integrator state for the current path. These are

+ * IntegratorState for passing state as read-only, to avoid oddities in typedef behavior.

-   *
-   * According to the standard reflection equation,
-   * this means that we want dot(2*dot(N', I)*N' - I, Ng) = t.
-   *
-   * Since the Z axis of our local coordinate system is Ng, dot(x, Ng) is just x.z, so we get
-   * 2*dot(N', I)*N'.z - I.z = t.
-   *
-   * The rotation is simple to express in the coordinate system we formed -
-   * since N lies in the X-Z-plane, we know that N' will also lie in the X-Z-plane,
-   * so N'.y = 0 and therefore dot(N', I) = N'.x*I.x + N'.z*I.z .
-   *
-   * Furthermore, we want N' to be normalized, so N'.x = sqrt(1 - N'.z^2).
-   *
-   * With these simplifications,
-   * we get the final equation 2*(sqrt(1 - N'.z^2)*I.x + N'.z*I.z)*N'.z - I.z = t.
-   *
-   * The only unknown here is N'.z, so we can solve for that.
-   *
-   * The equation has four solutions in general:
-   *
-   * N'.z = +-sqrt(0.5*(+-sqrt(I.x^2*(I.x^2 + I.z^2 - t^2)) + t*I.z + I.x^2 + I.z^2)/(I.x^2 + I.z^2))
-   * We can simplify this expression a bit by grouping terms:
-   *
-   * a = I.x^2 + I.z^2
-   * b = sqrt(I.x^2 * (a - t^2))
-   * c = I.z*t + a
-   * N'.z = +-sqrt(0.5*(+-b + c)/a)
