Hello Andrea,
Thank you, that is exactly what I was looking for!
After I've added a call to this method at the end of my program there's less "leaks", \
but some remain. Apparently the memory is allocated by certain pixman methods (stack \
trace attached). Maybe there's a method similar to cairo_debug_reset_static_data in \
pixman, too? I failed to find it so far. Or does it mean that something actually went \
wrong?
Cheers,
Mikhail
