I have one situation as follows:
(1) In my program, the initial invocation of cairo function:
is extremely slow, sometimes it takes about 60 seconds for this function to return;
(2) After the initial invocation of cairo_text_extents, any subsequent invocation of this
method becomes very fast, it returns in less than 1 second.
Why cairo_text_extents behaviors like this? Is there any way to solve this problem?
Thanks very much,
