/* 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
|

|
||
|
|
*
|
||
|
|
* 2008-05-23: Carl Worth wrote this test for the cairo test suite to
|
||
|
|
* exercise the bug.k
