Export meta-surface

The meta-surface is a vital tool to record a trace of drawing commands
in-memory. As such it is used throughout cairo.

The value of such a surface is immediately obvious and should be
applicable for many applications. The first such case is by
cairo-test-trace which wants to record the entire graph of drawing commands
that affect a surface in the event of a failure.

+Snapshot 1.9.4 (2009-07-xx)
+===========================
+API additions:
+
+  cairo_meta_surface_create()
+  cairo_meta_surface_ink_extents()
+  cairo_meta_surface_replay()
+
+    Finally exporting the internal meta-surface so that applications
+    have a method to record and replay a sequence of drawing commands.
+
+New utilities:
+
+  cairo-test-trace
+
+    A companion to cairo-perf-trace, this utility replays a trace against
+    multiple targets in parallel and looks for differences in the output,
+    and then records any drawing commands that cause a failure.
+    Future plans:
+      Further minimisation of the fail trace using "delta debugging".
+      More control over test/reference targets.
+
+New experimental backends:
+
+   QT
