Re: [alreq] Layout (flow direction) of math formula

@khaledhosny  Please disregard the digits glyph on images above. Which
 numbers' shapes (Arabic-European or Arabic-Indic) are used in 
different countries is "standardized" in CLDR:
Arabic numeric shaping (0123456789 vs. ٠ ١٢٣٤٥٦٧٨٩ vs. ...)  - appears
 as part of "Numbering systems" 
-http://cldr.unicode.org/translation/numbering-systems . For example 
http://www.unicode.org/repos/cldr/trunk/common/bcp47/number.xml or 
https://github.com/unicode-cldr/cldr-core/blob/master/supplemental/numberingSystems.json
 have 
 "٠ ١٢٣٤٥٦٧٨٩" defined as "arab" and "1234567890" defined as "latn". 
Mapping to locale is done via property  <defaultNumberingSystem> which
 is "arab" for ar 
(http://unicode.org/cldr/trac/browser/trunk/common/main/ar.xml) but  
"latn" for ar_MA 
(http://unicode.org/cldr/trac/browser/trunk/common/main/ar_MA.xml) and
 ar_DZ 
(http://unicode.org/cldr/trac/browser/trunk/common/main/ar_DZ.xml)

In this specific issue the point is in the formula direction (and 
possibly with flipping math symbols such as root symbol , sigma symbol
 etc.) not in numeric shaping.
