| /* Bug history: |
| * |
| * 2008-05-23: Caolan McNamara noticed a bug in OpenOffice.org where, |
| * when using a very large font, space would be left for a |
| * glyph but it would actually be rendered in the wrong |
| * place. He wrote a minimal test case and posted the bug |
| * here: |
| * |
| * corrupt glyph positions with large font |
| * https://bugzilla.redhat.com/show_bug.cgi?id=448104 |
| * |
| * 2008-05-23: Carl Worth wrote this test for the cairo test suite to |
| * exercise the bug. |
