406717 - [meta] Audit all uses of window frames for resolution-independence-unsafe assumptions

Status: RESOLVED INCOMPLETE

(Camino Graveyard :: General, defect)

Description

[Stuart Morgan]

Window frame coordinate systems cannot be assumed to be the same as those of view (and therefore Gecko) coordinates. We violate this in a bunch of places; from a very rough first pass, this likely includes:
- window sizing and positioning from Gecko (BrowserWrapper's sizeBrowserTo:, CHBrowserListener's Get/SetDimensions)
- sizing and positioning of AutoCompleteTextField's dropdown
- tooltip positioning
- hideChangePasswordField in BrowserSecurityDialog

The above is just from looking at setFrame:; there's almost undoubtedly more where we get and do computation with the window frame. I'll file a bug for the first, which I've verified and started to fix, and we can file more as we verify them.

This is probably low-priority for 2.0 given that OS-level resolution independence has problems in Gecko 1.9.0, but it would be good to get our stuff in order if we have time.

... which we don't realistically.
