This new test exercises every path where the user might possibly pass in an invalid matrix. Currently the test fails if no error is reported. Also, if an incorrect error is reported, (such as CAIRO_STATUS_NO_MEMORY instead of CAIRO_STATUS_INVALID_MATRIX), this is logged as a warning in invalid-matrix.log, but the test still passes. It would still be worthwhile to follow up quickly and fix those cases to propagate the correct error value.
