Added trace graphics system for painting performance profiling.

When running an application with graphics system trace everything that
gets painted to the window surface is proxied through a QPaintBuffer,
which is then both streamed to a trace file and replayed on a raster
window surface. The trace file can then be replayed with
tools/qttracereplay to measure pure painting performance.
