cairo 1.0.2 contains fix for crash in OOo cairo canvas

Behavior and API changes
------------------------
 * Setting the filter on a gradient pattern would change the
   interpolation between color stops away from the normal linear
   interpolation. This dubious behavior has been removed.

 * The CAIRO_CONTENT_VALID() and CAIRO_FORMAT_VALID() macros --
   implementation details that leaked into cairo.h -- have been moved
   into an internal header.

 * The cairo_show_text function now advances the current point
   according to the total advance values of the string.

API additions
-------------
 * cairo_set_dash can now detect error and can set
   CAIRO_STATUS_INVALID_DASH.


so number goes from libcairo.so.2.1.1 to libcairo.so.2.2.3
