Re: extended zvt widget

[Cristiano De Michele <demichel na infn it>]

Hi,
I gave a quick look at zvt accessibility sources and 
there shouldn't anything broken though we need to check 
of course, anyway the only problem I saw is that
I extended the line zvt struct adding for each char a unsigned 
char to put extra attributes such as that related to SPA/DEC
protected modes,
in fact zvt_term_get_buffer works exactly in the same way...
