.SH "DESCRIPTION"
This function does the Arabic joining algorithm. Means, given Arabic
joining types of the characters in ar_props (don't worry,
FriBidiJoiningType can be casted to FriBidiArabicProp automagically), this
function modifies this properties to grasp the effect of neighboring
characters. You probably need this information later to do Arabic shaping.
This function implements rules R1 to R7 inclusive (all rules) of the Arabic
Cursive Joining algorithm of the Unicode standard as available at
http://www.unicode.org/versions/Unicode4.0.0/ch08.pdf#G7462. It also
interacts correctly with the bidirection algorithm as defined in Section
.br
3.5 Shaping of the Unicode Bidirectional Algorithm available at
http://www.unicode.org/reports/tr9/#Shaping.
There are a few macros defined in fribidi-joining-types.h for querying the
Arabic properties computed by this function.
