/* Comment from glut.h of classic GLUT:
Win32 has an annoying issue where there are multiple C run-time
libraries (CRTs). If the executable is linked with a different CRT
from the GLUT DLL, the GLUT DLL will not share the same CRT static
data seen by the executable. In particular, atexit callbacks registered
in the executable will not be called if GLUT calls its (different)
exit routine). GLUT is typically built with the
"/MD" option (the CRT with multithreading DLL support), but the Visual
C++ linker default is "/ML" (the single threaded CRT).
One workaround to this issue is requiring users to always link with
the same CRT as GLUT is compiled with. That requires users supply a
non-standard option. GLUT 3.7 has its own built-in workaround where
the executable's "exit" function pointer is covertly passed to GLUT.
GLUT then calls the executable's exit function pointer to ensure that
any "atexit" calls registered by the application are called if GLUT
needs to exit.
Note that the __glut*WithExit routines should NEVER be called directly.
To avoid the atexit workaround, #define GLUT_DISABLE_ATEXIT_HACK. */

/*************************************************************************
The main program.
This class provides the functionality of the main program. The program
starts after calling the "run" method. This method initializes the GLUT
system for rendering (using OpenGL) and user interaction. During the
initialization process different methods are connected to certain events
such as "display the window content", "act on mouse motion and buttons"
or "act on key events". Furthermore the main context menu is initialized
by calling the method "setup_context_menu".
Whenever one of the events described above occurs the appropriate functions
are called (They are however not called directly but via static functions
that forward the event. Read the included PDF if you are interested why
this is done and how it works).
The class maintains an instance of an tool_base which is initialized
to a concrete tool in the "context_menu_select" method.
The rendering of the canvas is done by an instance of "canvas_renderer"
while the data storage and modification operations are part of the class
"canvas_buffer".

Template class for vectors.
This template class defines small vectors of a defined dimension with
an arbitrary data type. Basic operations such as addition of vectors and
multiplication of a vector and a scalar are supported via operator
overloading. Also more advanced functions such as normalization and
iterating through the elements are implemented.
At the end of this file the data types "point2d", "point3d" and
"point4d" are specified as a tinyvec of doubles with the according dimension.

Abstract tool.
This class provides the basic superclass for all tools (pen, lines, circle...)
The constructor of the class takes a reference of a canvas_buffer as parameter
on which the pixels are changed.
The user of an instance of a derived class can use two different draw methods:
One version that operates only with the information of a single position
(e.g. the pen or the fill tools) and one that needs two pixel positions
(e.g. the line, circle or box). Also every tool maintains an element of
the enumerations of possible shapes (which are used for the preview tool).
For debugging purpose a method "set_text" is provided which modifies a
text stream that will be displayed in the main window.

"canvas.set_pixel(x, y)" um einen Pixel zu setzen, wobei
"x" und "y" den gewünschten Pixelpositionen entsprechen.
Diese Methode behandelt auch Randverletzungen. Stellen Sie zunaechst
den Standardfall her. Falls Sie den Wert zweier Variablen vertauschen
muessen koennen Sie dafür die Methode "std::swap(a, b)" verwenden.

think about when to set the pixel (at the beginning of the loop or after
