Use qt_draw_glyphs() to implement a QPaintBuffer::drawStaticText() which
will actually replay via drawStaticTextItem() on engines that support
it.

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.

QStaticText was previously made private API to support inclusion in
Qt 4.6.x. This change turns it back into public API for Qt 4.7.0.

We can't add new symbols to QPainter for Qt 4.6.x, as we would not be
able to remove them again if we regretted the API. Hence, I've made
removable symbols instead, a private global function and a
drawStaticText() in QPainterPrivate. In order to tie things together,
I needed a static private-getter in QPainterPrivate, and hence it
had to be a friend of QPainter.

No reason to look through all the commands, since we have the transform
saved in the state.

Turns QStaticText into private API in preparation for Qt 4.6.x. The
related functions in QPainter are marked as internal in the docs. There
are already internal functions in QPainter, so this seemed like a
reasonable solution. Since the functions require QStaticText they will
not be accessible to anyone who does not include private API.

Compile QStaticText and also use font object in QPaintBuffer since it's
now available
|
| |
|
|
|
|

Make QPaintEngineEx::drawStaticTextItem() pure virtual to make sure
it's implemented in all engines, and implement the paint buffer version
to make gui compile.

Q_DECLARE_METATYPE must appear before qRegisterMetaType.

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.

This reduces the size of the trace files significantly in certain cases.

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.
