<p>Anyway, I think we could merge the proposed code refactoring. However, please keep the TODO comments.</p></div></div><br /><div><strong>INLINE COMMENTS</strong><div><div style="margin: 6px 0 12px 0;"><div style="border: 1px solid #C7CCD9; border-radius: 3px;"><div style="padding: 0; background: #F7F7F7; border-color: #e3e4e8; border-style: solid; border-width: 0 0 1px 0; margin: 0;"><div style="color: #74777d; background: #eff2f4; padding: 6px 8px; overflow: hidden;"><a style="float: right; text-decoration: none;" href="https://phabricator.kde.org/D28708#inline-164695">View Inline</a><span style="color: #4b4d51; font-weight: bold;">abstract_egl_backend.cpp:482-486</span></div>
