4 | Subject: [PATCH] Add new perf test "pattern_create_radial" | ||
5 | |||
6 | This test is really just for hammering the double to fixed-point conversion | ||
7 | (in _cairo_fixed_from_double) that happens as doubles from API calls gets | ||
8 | translated into internal cairo fixed-point numbers. | ||
9 | |||
10 | Because it's not generally useful, I don't recommend that it become part of | ||
11 | the main cairo performance test. But hey, it might come in handy for someone | ||
12 | else. | ||
