Bounce uses premake for generating project files in a platform agnostic manner.
Grab premake from http://industriousone.com/premake.
Put premake.exe into bounce/.
Visual Studio 2015
Open bounce/bat.
Open premake_vs2015.bat. This will run a premake script and open bounce/build/vs2015/bounce.sln.
Set testbed as the startup project.
Press F5 or Ctrl-F5 to run.
premake files for building on Mac will be available later because I don't run Mac currently and
therefore can't test the build system in this platform.

Generating API Documentation
Grab Doxygen from http://www.doxygen.org
Say the following on the command line: doxygen doxyfile
Open doc/api/html/index.html
User manual is a work in progress. Meanwhile, code comments are the best way to learn how to use
Bounce.

/* Khronos platform-specific types and definitions.

* $Revision: 32517 $ on $Date: 2016-03-11 02:41:19 -0800 (Fri, 11 Mar 2016) $
*
* Adopters may modify this file to suit their platform. Adopters are
* encouraged to submit platform specific modifications to the Khronos
* group so that they can be included in future versions of this file.
* Please submit changes by sending them to the public Khronos Bugzilla
* (http://khronos.org/bugzilla) by filing a bug against product
* "Khronos (general)" component "Registry".
*
* A predefined template which fills in some of the bug fields can be
* reached using http://tinyurl.com/khrplatform-h-bugreport, but you
* must create a Bugzilla login first.
*
*
* See the Implementer's Guidelines for information about where this file
* should be located on your system and for more details of its use:
* http://www.khronos.org/registry/implementers_guide.pdf
*
* This file should be included as
* #include <KHR/khrplatform.h>
* by Khronos client API header files that use its types and defines.
*
* The types in khrplatform.h should only be used to define API-specific types.
*
* Types defined in khrplatform.h:
* khronos_int8_t signed 8 bit
* khronos_uint8_t unsigned 8 bit
* khronos_int16_t signed 16 bit
* khronos_uint16_t unsigned 16 bit
* khronos_int32_t signed 32 bit
* khronos_uint32_t unsigned 32 bit
* khronos_int64_t signed 64 bit
* khronos_uint64_t unsigned 64 bit
* khronos_intptr_t signed same number of bits as a pointer
* khronos_uintptr_t unsigned same number of bits as a pointer
* khronos_ssize_t signed size
* khronos_usize_t unsigned size
* khronos_float_t signed 32 bit floating point
* khronos_time_ns_t unsigned 64 bit time in nanoseconds
* khronos_utime_nanoseconds_t unsigned time interval or absolute time in
* nanoseconds
* khronos_stime_nanoseconds_t signed time interval in nanoseconds
* khronos_boolean_enum_t enumerated boolean type. This should
* only be used as a base type when a client API's boolean type is
* an enum. Client APIs which use an integer or other type for
* booleans cannot use this as the base type for their boolean.
*
* Tokens defined in khrplatform.h:
*
* KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
*
* KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
* KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
*
* Calling convention macros defined in this file:
* KHRONOS_APICALL
* KHRONOS_APIENTRY
* KHRONOS_APIATTRIBUTES
*
* These may be used in function prototypes as:
*
* KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
* int arg1,
* int arg2) KHRONOS_APIATTRIBUTES;

*
* **By using the native access functions you assert that you know what you're
* doing and how to fix problems caused by using them. If you don't, you
* shouldn't be using them.**
*
* Before the inclusion of @ref glfw3native.h, you may define exactly one
* window system API macro and zero or more context creation API macros.
*
* The chosen backends must match those the library was compiled for. Failure
* to do this will cause a link-time error.
*
* The available window API macros are:
* * `GLFW_EXPOSE_NATIVE_WIN32`
* * `GLFW_EXPOSE_NATIVE_COCOA`
* * `GLFW_EXPOSE_NATIVE_X11`
* * `GLFW_EXPOSE_NATIVE_WAYLAND`
* * `GLFW_EXPOSE_NATIVE_MIR`
*
* The available context API macros are:
* * `GLFW_EXPOSE_NATIVE_WGL`
* * `GLFW_EXPOSE_NATIVE_NSGL`
* * `GLFW_EXPOSE_NATIVE_GLX`
* * `GLFW_EXPOSE_NATIVE_EGL`
*
* These macros select which of the native access functions that are declared
* and which platform-specific headers to include. It is then up your (by
* definition platform-specific) code to handle which of these should be
* defined.

/*
* Marcus: This code was originally written by Markus G. Kuhn.
* I have made some slight changes (trimmed it down a bit from >60 KB to
* 20 KB), but the functionality is the same.
*/
/*
* This module converts keysym values into the corresponding ISO 10646
* (UCS, Unicode) values.
*
* The array keysymtab[] contains pairs of X11 keysym values for graphical
* characters and the corresponding Unicode value. The function
* _glfwKeySym2Unicode() maps a keysym onto a Unicode value using a binary
* search, therefore keysymtab[] must remain SORTED by keysym value.
*
* We allow to represent any UCS character in the range U-00000000 to
* U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
* This admittedly does not cover the entire 31-bit space of UCS, but
* it does cover all of the characters up to U-10FFFF, which can be
* represented by UTF-16, and more, and it is very unlikely that higher
* UCS codes will ever be assigned by ISO. So to get Unicode character
* U+ABCD you can directly use keysym 0x0100abcd.
*
* Original author: Markus G. Kuhn <mkuhn@acm.org>, University of
* Cambridge, April 2001
*
* Special thanks to Richard Verhoeven <river@win.tue.nl> for preparing
* an initial draft of the mapping table.

// stb_rect_pack.h - v0.08 - public domain - rectangle packing
// Sean Barrett 2014
//
// Useful for e.g. packing rectangular textures into an atlas.
// Does not do rotation.
//
// Not necessarily the awesomest packing method, but better than
// the totally naive one in stb_truetype (which is primarily what
// this is meant to replace).
//
// Has only had a few tests run, may have issues.
//
// More docs to come.
//
// No memory allocations; uses qsort() and assert() from stdlib.
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
//
// This library currently uses the Skyline Bottom-Left algorithm.
//
// Please note: better rectangle packers are welcome! Please
// implement them to the same API, but with a different init
// function.
