The files in this directory go in the "handmade/code" directory
for Day 012 of Handmade Hero. In particular, it _will not compile_
without the handmade.h and handmade.cpp files from the Day 012 source.

They correspond to Chapter 12 of the Handmade Penguin tutorial at
http://davidgow.net/handmadepenguin/ch12.html

"sdl_handmade.cpp" is the version with the custom ringbuffer can be compiled with:
./build.sh

"sdl_handmade_queueaudio.cpp" is the version using SDL_QueueAudio(), and can be
compiled with:
./build-queueaudio.sh

Both versions produce a ./handmadehero binary.

A custom copy of SDL is used for the SDL_QueueAudio() version. As a result,
it will not work if the binary is moved to another directory, unless your system
version of SDL2 supports the SDL_QueueAudio() function.

Unless there any any complaints, future versions of the source download will not
include the SDL_QueueAudio version. Post in the forums or email me if you want
to save the endangered buffer queueing system.

Don't bug Casey about this code, the bugs in it are David Gow's
fault, and should be reported to <david@ingeniumdigital.com> or posted in the 
discussion thread on the forums:

Enjoy,
