IF you're going to fix issues with writing system directionality, consider all
of the directions that writing systems move in:

    • The Writing starts at the Bottom of the page moving up To the Top of the
page, Vertically, with lines running from the Left hand side To Right hand side
of the page. IOW, successive lines are to the right of each other;
    • The Writing starts at the Bottom of the page moving up to the Top of the
page, Vertically, with lines running from the Right hand side To the Left hand
side of the page. IOW, successive lines are to the left of each other;
    • The writing starts at the Top of the page, moving down To the Bottom of
the page, Vertically, with lines running from the Left hand side of the page To
the Right hand side of the page. IOW, successive lines are to the right of each
other;
    • The writing starts at the Top of the page, moving down To the Bottom of
the page, Vertically, with lines running from the Right hand side of the page
To the Left hand side of the page. IOW, successive lines are to the left of
each other;
    • The writing starts on the Left hand side of the page, moving To the Right
hand side of the page, Horizontally, from the Bottom of the page To the Top of
page. IOW, successive lines are above each other;
    • The writing starts on the Left hand side of the page, moving To the Right
hand side of the page, Horizontally, from the Top of the page To the Bottom of
the page. IOW, successive lines are below each other;
    • The writing starts on the Left hand side of the page, moving To the Right
hand side of the page, Vertically, from the Bottom of the page To the Top of
the page;
    • The writing starts on the Left hand side of the page, moving To the Right
hand side of the page,Vertically, from the Top of the page To the Bottom of the
page;
    • The writing starts on the Right hand side of the page, moving To the Left
hand side of the page, Horizontally, from the Bottom of the page To the Top of
the page. IOW, successive lines are above each other;
    • The writing starts on the Right hand side of the page, moving To the Left
hand side of the page, Horizontally, from the Top of the page To the Bottom of
the page;
    • The writing starts on the Right hand side of the page, moving To the Left
hand side of the page, Horizontally, from the Top of the page To the Bottom of
the page. IOW, successive lines are below each other;
    • The writing starts on the Right hand side of the page, moving To the Left
hand side of the page, Vertically, from the Bottom of the page To the Top of
the page;
    • The writing starts on the Right hand side of the page, moving To the Left
hand side of the page, Vertically, from the Top of the page To the Bottom of
the page;
    • The writing starts on the Right hand side of the page, moving To the Left
hand side of the page,Horizontally, from the Bottom of the page To the Top of
the page;
    • Boustropedon: The writing direction alternates on each line;
    • Boustropedon Clockwise: The writing direction is circular, moving in a
clockwise direction;
    • Boustropedon Counter Clockwise: The writing direction is circular, moving
in a counter-clockwise direction;
    • Reverse Boustropedon: The writing direction alternates on each line, with
glyphs on alternate lines being upside down, in relation to the preceeding and
successive line;
    • Reverse Boustropedon Clockwise: The writing direction is circular, moving
in a clockwise direction, with glyphs on opposite side being upside down, in
relation to each other;
    • Reverse Boustropedon Counter Clockwise: The writing direction is
circular, moving in a counter clockwise direction, with glyphs on opposite side
being upside down, in relation to each other;

Writing systems with the following writing directions require additional
hardware, and the appropriate drivers for that hardware, if they are to be
correctly supported by LibreOffice.
(FWIW, LibreOffice no longer supports the most commonly used writing system
within this category).
    • 3-Dimensional;
    • 4-Dimensional;
    • Non-Linear;

Writing systems with the following writing direction, can only be used by using
_Draw_;
As far as I know, the only writing systems that utilize these writing
directions are conlang writing systems;
