Subject: Evas textblock: cursor_geometry_get now also returns the direction of the cursor... 
X-Git-Tag: submit/trunk/20120815.174732~2413
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b9322923f4d5d5c9a89e8fd3c5b8665a0e287e74;p=profile%2Fivi%2Fevas.git

Evas textblock: cursor_geometry_get now also returns the direction of the cursor: rtl/ltr/whatever.
Fixed documentation a bit.
