* This is a native Win32 port of the Borgware-2D API simulator. Although the

* OpenGL based simulator is in fact platform independent, there are some
|

* obstacles regarding Cygwin's OpenGL support.
|
||||
*
|
||||
* Earlier versions of Cygwin used to ship bindings to Win32's native OpenGL
|
||||
* libraries. Unfortunately some of those native components (GLUT in particular)
|
||||
* weren't maintained for years so it was decided to cease support for them.
|
||||
*
|
||||
* The reasons are explained in more detail at
|
||||
* http://cygwin.com/ml/cygwin/2012-05/msg00276.html
|
||||
*
|
||||
* The OpenGL bindings which are now shipped with Cygwin require a running
|
||||
* X-Server which I consider clumsy to use on a Windows platform (especially for
|
||||
* a small application like this simulator). So I decided to write a native
|
||||
* Win32 application to free Windows developers from the hassles of rolling out
|
||||
* a complete X11 setup.
|
||||
*
|
||||
* The native simulator feels like the OpenGL based one, with the exception that
|
||||
* you can't rotate the matrix (I'm using the plain GDI32 API for the graphics).
