Cut and paste and right-to-left or column text

solved:
unsolvedWhen cutting and pasting JSesh text in word/openoffice, etc. the text is pasted as left-to-right text.
It's more a unwritten feature than a bug (that is, I know what to do, but I haven't written the code yet).
Temporary Workaround:
You can choose how the text will be copied in the menu "Tools/Edit Preference" (see the documentation). Simply choose one of "as one large picture" (which will give you an exact rendering) or "grouped cadrats" (which will give correct right-to-left text, except if there is a mix of latin text and hieroglyphs).
