Added new --instrumentframe=X argument which gives a detailed run-down
of how many milliseconds each paint command of that frame takes.

A couple of improvements have been made:
* Use single precision floats for the traces.
* Reduce the number of variant wrapped transforms by introducing a new
translate command.
* Reduce the number of bytes streamed per image / pixmap draw command.
* Add versioning info to qttrace files to be more future proof.

Makes it easy to split a large trace into several sub-traces by running
the qttracereplay with -graphicssystem trace.

This lets us stream a single QPaintBuffer instead of one QPaintBuffer
per frame in the trace graphicssystem, which leads to not streaming
pixmaps / images once per frame. Performance when doing a trace is also
a lot better for painting heavy applications.

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.
