[cairo] [PATCH 5/5] fallback: Silence gcc warning

[Andrea Canciani]

gcc complains that

cairo-surface-wrapper.c:647: warning: ignoring return value of
‘_cairo_rectangle_intersect’, declared with attribute warn_unused_result

Storing the result in a variable (which is otherwise unused) makes gcc
happy.
