    \section JKQTMathTextSuppoertedLaTeXMathTextMode Switch between Math- and Text-Mode
    
    These LaTeX-instructions allow to switch between math and text-mode:
      - \c $...$ , \c \\ensuremath{...} , \c \\equation{...} : inside is math-mode
      - \c \\text{...} , \c \\mbox{...} , \c \\ensuretext{...} : switches from math back to text-mode (or stays in text-mode)
    .
    
    The following image shows the difference between text- and math-mode:
    
    \image html jkqtmathtext/jkqtmathtext_mathmode_and_textmode.png
    
    In text mode the text is rendered normally. In math mode the rendering is changed:
      - normal text is typeset in an italic font
      - numbers, parantheses ... are typeset in an upright font
      - operators are typeset with additional space around them
    .
    
    \section JKQTMathTextSuppoertedLaTeXFontProps Font Properties
    The supported LaTeX subset is listes below. Please note that some commands are used differently than in actual LaTeX.
    For example \c \\bf is just a renamed form of \c \\textbf and used as \c \\bf{...} and NOT as \c {\\bf...} .

    .

   
    \section JKQTMathTextSuppoertedLaTeXVerbatim Verbatim Text
    Sometimes it is necessary to typeset text withou interpreting it as LaTeX markup. These instructions are implemented for that:
      - <code>\\verb!...!</code>: interpret enclosed text between \c ! as verbose. Instead of \ ! you can choose ANY character! \image html jkqtmathtext/jkqtmathtext_verb.png generated by <code>\\verb!\\LaTeX{} is not pares inside \\verb~..~! outside {\\backslash}verb</code>
      - <code>\\begin{verbatim}...\\end{verbatim}</code>: interpret enclosed multi-line text as verbatim. \image html jkqtmathtext/jkqtmathtext_verbatim.png generated by <code>outside\\begin{verbatim}\ninside \\LaTeX verbatim\n  2nd verbaimline\n\t3rd line\n\\end{verbatim}</code>
      - <code>\\begin{lstlisting}...\\end{lstlisting}</code>: actually menat for highlighted code, for now this is the same as \c \\begin{verbatim}...\\end{verbatim}. \image html jkqtmathtext/jkqtmathtext_lstlisting.png generated by <code>outside\\begin{lstlisting}\nint main() {\n  printf("Hello World\\n");\n}\n\\end{lstlisting}</code>
      - <code>\\begin{verbatim*}...\\end{verbatim*}</code>: interpret enclosed multi-line text as verbatim. Print with visible whitespace and tab characters \image html jkqtmathtext/jkqtmathtext_verbatimast.png generated by <code>outside\\begin{verbatim*}\ninside \\LaTeX verbatim\n  2nd verbaimline\n\t3rd line\n\\end{verbatim*}</code>
    .

    
    \section JKQTMathTextSuppoertedLaTeXSymbols Symbols and special characters

    These instructions draw boxes in various ways:
      - \c \\alpha ... : display the according greek letter \image html jkqtmathtext/jkqtmathtext_greek.png
      - \c \\charDECIMAL and \c \\char\"HEX and \c \\char\'OCTAL : draws a unicode character from its 32-bit codepoint \image html jkqtmathtext/jkqtmathtext_char.png (generated by <code>A: \\char65, circonflex: \\char\"109 accent: \\char\'351</code>)

      - \c \\{ / \\} : display opening/closing brace
      - \c \\_ : display underscore

                                          symbols may differ (there are not all symbols defined in the MS Windows Symbol
                                          font!). Best coverage should be given by Unicode font encoding with a good
                                          unicode font installed!<br>\image html jkqtmathtext/jkqtmathtext_symbols.png

    .
    
    
    \section JKQTMathTextSuppoertedLaTeXMathSupport Supported Mathematical Constructs

    \subsection JKQTMathTextSuppoertedLaTeXSubSuper Sub- and Superscript
    The standard LaTeX sub-/superscript instructions (i.e. \c text_{sub} or \c text^{super} ) are supported:
         - \c ^{...} \c _{...} : display the contents of braces in superscript/subscript \image html jkqtmathtext/jkqtmathtext_supersub.png
        <br>Special subscript/superscript typesetting applies, when the sub/super follows \c \\sum \c \\Prod ...: \image html jkqtmathtext/jkqtmathtext_specialsubsuper.png
    .
 
    \subsection JKQTMathTextSuppoertedLaTeXBraces Braces/Parantheses ...
    Braces in math mode are adjusted in size, so they are a small bit (factor \c brace_factor ) larger than the contents.
    To enable this you have to write braces with \c \\left and \c \\right. These types of braces are defined (slight
    differences to LaTeX standard):
      - \c \\left( \c \\right) : default meaning (), \image html jkqtmathtext/jkqtmathtext_brace_round.png
      - \c \\left[ \c \\right] : default meaning [], \image html jkqtmathtext/jkqtmathtext_brace_rect.png
      - \c \\left\\{ \c \\right\\} : default meaning {}, \image html jkqtmathtext/jkqtmathtext_brace_curly.png
      - \c \\left\\langle \c \\right\\rangle : "averaging" braces , \image html jkqtmathtext/jkqtmathtext_brace_tri.png
      - \c \\left\\lfloor \c \\right\\rfloor : floor braces , \image html jkqtmathtext/jkqtmathtext_brace_floor.png
      - \c \\left\\lceil \c \\right\\rceil : ceil braces , \image html jkqtmathtext/jkqtmathtext_brace_ceil.png
      - \c \\left| \c \\right| : absolute value braces | |, \image html jkqtmathtext/jkqtmathtext_bracejkqtmathtext_brace_ucorner_oneline.png
      - \c \\left\\| \c \\right\\| \endcode : norm braces || ||, \image html jkqtmathtext/jkqtmathtext_brace_dblline.png
      - \c \\left\\llcorner \c \\right\\lrcorner : lower corner braces , \image html jkqtmathtext/jkqtmathtext_brace_lcorner.png
      - \c \\left\\ulcorner \c \\right\\urcorner : upper corner braces , \image html jkqtmathtext/.png
      - You can use \c \\left. or \c \\right. to have only right or only left brace
    .
    
    In additional fixed-size parantheses are available with the following family of instructions:
      - \c \\bigl([\\{\\langle... , \c \\big([\\{\\langle... and \c \\bigr)]\\}\\rangle... \image html jkqtmathtext/jkqtmathtext_brace_big.png
      - \c \\Bigl([\\{\\langle... , \c \\Big([\\{\\langle... and \c \\Bigr)]\\}\\rangle... \image html jkqtmathtext/jkqtmathtext_brace_bbig.png
      - \c \\biggl([\\{\\langle... , \c \\bigg([\\{\\langle... and \c \\biggr)]\\}\\rangle... \image html jkqtmathtext/jkqtmathtext_brace_bigg.png
      - \c \\Biggl([\\{\\langle... , \c \\Bigg([\\{\\langle... and \c \\Biggr)]\\}\\rangle... \image html jkqtmathtext/jkqtmathtext_brace_bbigg.png
    .
    They use the same rendering code as the standard \c \\left and \c \\right instructions. Here is an example:
    \image html jkqtmathtext/jkqtmathtext_brace_bigfamily.png generated by <code> $\Biggl\langle\biggl\{\Bigl[\bigl( r^{123}\bigr)\Bigr]\biggr\}\Biggr\rangle$</code>

    \subsection JKQTMathTextSuppoertedLaTeXRoots Roots
    There are also instructions that allow to write roots:
      - <code>$\\sqrt{1+\\sqrt{1+x}}$</code> \image html jkqtmathtext/jkqtmathtext_sqrt.png
      - <code>$\\sqrt[3]{1+\\sqrt[3]{1+x}}$</code> \image html jkqtmathtext/jkqtmathtext_cbrt.png
    .

    \subsection JKQTMathTextSuppoertedLaTeXUnderOver Undersetting, Oversetting, Underbraces, Overbraces ...
    There are also instructions that allow to under/overset braces, arrows, ...:
