Subject: Initial support for continuous spell-checking. This is far from working perfectly... 
X-Git-Tag: 2.0.0~6721
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=ea54380e136ceb0d4a3ce43f67456c0db562b6ce;p=lyx.git

Initial support for continuous spell-checking. This is far from working perfectly. I reused the word completion framework to achieve this. This doesn't seem to have sensible effect over edition speed.

You'll need to check the continuous spellcheck option in order to test this.
