Come hear about the work on the Visual Class Library (VCL) in the last year - the bottom of the cross-platform graphics system that LibreOffice is built on. See how we've re-factored the per-platform backends, improved the lifecycle mechanism (VclPtr), re-vamped our main-loop (the idle handler re-work) as well as many other long overdue improvements. Also hear about how we're using OpenGL to accelerate rendering and improve quality.
