Minimal D3D11 part 3

An elaboration on Minimal D3D11 pt2, adding shadowmapping and incorporating various improvements and alternative approaches to the rendering setup, such as manual vertex fetching, samplerless texture lookup, null shader depth map rendering and procedurally generated texture and instance data.

As before, this is intended to be an an "API familiarizer" - an uncluttered Direct3D 11 setup & basic rendering reference implementation, in the form of a complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion. No modern C++ / OOP / obscuring cruft, only ~190 LOC. View on YouTube

Minimal D3D11

Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++, OOP or (other) obscuring cruft. View on YouTube

Minimal D3D11 part 2

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

1. Combined type and variable/field declaration, inside a struct scope [https://godbolt.org/g/Rh94Go]

struct foo {
   struct bar {
 int x;
