[Lazarus] Examples of CairoCanvas usage

[Juha Manninen]

Strange.
I am testing on Windows, Gtk+ for Windows runtime environment is installed.
My project depends on cairocanvas_pkg.lpk

When I run the test below without the TextOut line, it works and file
"abcdef.pdf" indeed contains an ellipse.
With the TextOut line it throws a SIGFPE. I cannot step into the
method even with all debug info enabled.
In Assembler debug window I can see it happened in
_cairo_win32_font_face_scaled_font_create.

Ideas? How to solve it? Could it be some missing DLL? It did not
complain about DLLs.
Am I doing something very stupid? It is possible because I have
limited experience with graphics and canvas methods.
