Details

The font embedded in that SWF gets discarded due to a malformed maxp table, leading to the Canvas API not drawing some text at all.

Definitely needs to be fixed before launch, but not before enabling in Nightly.

No longer blocks: shumway-m3
SWF #477 is another example: http://swf.codeazur.com.br/?tag=#87c6a8b534960b431bbacfb5d258f9958cb641cbce2f7d848dcc5ee2196606c5 downloadable font: maxp: bad max_zones: 0 (font-family: "swffont20" style:normal weight:normal stretch:normal src index:0)

Turned out that this was related to clipping, not font issues. Anyway, the irritating errors thrown by the font sanitizer will be fixed in https://github.com/mozilla/shumway/pull/2126 whereas the actual issue here is addressed in https://github.com/mozilla/shumway/pull/2125.
