1209703 - Make sync decoding work for border-image

Status: RESOLVED FIXED

(Core :: Layout: Images, Video, and HTML Frames, defect)

Description

[Seth Fowler [:seth] [:s2h]]

Currently sync decoding does not work for border-image. Our reftests pass most of the time due to lucky timing. (Though there are some low-level intermittents on Orangefactor.) The changes made in bug 1207355 *really* expose this issue, though, so we need to fix this to land that bug.

Unfortunately there are *lots* of issues to sort out here. Consider this a metabug; I'll hang other bugs off of this one that actually fix the various problems.

This shouldn't get reviewed or land, but just for reference: this patch makes it
easy to reproduce the intermittent oranges I'm trying to debug here, by sleeping
for one second in Decoder::Decode().
