I'm running KDE on Slackware 14.1. I'd like to be able to highlight sections of PDF files using Okular's annotation toolbar. The version that ships with Slackware 14.1 appears to only allow you to highlight in yellow. Newer versions of Okular allow you to configure your annotations toolbar so that you can add other colors to the toolbar:

Is it possible to upgrade to a newer version of Okular without upgrading KDE as a whole?
