550469 - [PageInfo] Sync changes from mozilla-central

Status: RESOLVED FIXED

(SeaMonkey :: Page Info, defect)

Description

[Philip Chee]

Port relevant patches from minefield pageInfo.

[Bug 494808] Page Info > Media doesn't list background images anymore.
[Bug 519390] Page info sometimes resizes an image incorrectly when it uses scaling.
[Bug 525190] Refactor the way pageInfo.js handles arguments.
[Bug 523047] Slow selectors in browser css)

I didn't bother with patches that dealt with the fallout from removing metadata.xul (because the code there was confusing and unmaintainable). And then repurposing PageInfo as a faux "View Image Properties". This mashup resulting in confusing and unnecessarily convoluted code (and they are /still/ at it).

I was thinking, "why this change", and then, "why was it commented out?"...

This seems familiar, it seems my tree already had this change ;-)

Yeah I tracked this down as well. Since there was no comment and Firefox doesn't have this and nobody has complained I thought it was time to rm.

Actually, it does have it (uncommented)

So enable it or just leave it uncommented?
